When terminated into a non-radiating RF load, the base station equipment is certied to comply with Federal Communications Commission (FCC) regulations pertaining to human exposure to RF radiation in accordance with the FCC Rules Part 1 section 1.1310 as published in title 47 code of federal regulations and procedures established in TIA/EIA TSB92, Report on EME Evaluation for RF Cabinet Emissions Under FCC MPE Guidelines, Compliance to FCC regulations of the nal installation should be assessed and take into account site specic characteristics such as type and location of antennas, as well as site accessibility of occupational personnel (controlled environment) and the general public (uncontrolled environment). This equipment should only be installed and maintained by trained technicians. Licensees of the FCC using this equipment are responsible for insuring that its installation and operation comply with FCC regulations Part 1 section 1.1310 as published in title 47 code of federal regulations. Whether a given installation meets FCC limits for human exposure to radio frequency radiation may depend not only on this equipment but also on whether the environments being assessed are being affected by radio frequency elds from other equipment, the effects of which may add to the level of exposure. Accordingly, the overall exposure may be affected by radio frequency generating facilities that exist at the time the licensees equipment is being installed or even by equipment installed later. Therefore, the effects of any such facilities must be considered in site selection and in determining whether a particular installation meets the FCC requirements. FCC OET Bulletin 65 provides materials to assist in making determinations if a given facility is compliant with the human exposure to RF radiation limits. Determining the compliance of transmitter sites of various complexities may be accomplished by means of computational methods. For more complex sites direct measurement of power density may be more expedient. Additional information on the topic of electromagnetic exposure is contained in the Motorola Standards and Guidelines for Communications Sites installation of this equipment are urged to consult the listed reference material to assist in determining whether a given installation complies with the applicable limits. In general the following guidelines should be observed when working in or around radio transmitter sites:
publication. Persons responsible for
- All personnel should have electromagnetic energy awareness training.
- All personnel entering the site must be authorized.
- Obey all posted signs.
- Assume all antennas are active.
- Before working on antennas, notify owners and disable appropriate transmitters.
- Maintain minimum 3 feet clearance from all antennas.
- Do not stop in front of antennas.
- Use personal RF monitors while working near antennas.
- Never operate transmitters without shields during normal operation.
- Do not operate base station antennas in equipment rooms. 68P80801E35-A 9/1/2001 23 System Installation and Testing General Safety Information EBTS System Manual - Vol 1 For installations outside of the U.S., consult with the applicable governing body and standards for RF energy human exposure requirements and take necessary steps for compliance with local regulations.

Licensees of the FCC using this equipment are responsible for insuring that its installation and operation comply with FCC regulations Part 1 section 1.1310 as published in title 47 code of federal regulations. Whether a given installation meets FCC limits for human exposure to radio frequency radiation may depend not only on this equipment but also on whether the environments being assessed are being affected by radio frequency elds from other equipment, the effects of which may add to the level of exposure. Accordingly, the overall exposure may be affected by radio frequency generating facilities that exist at the time of the licensees equipment is being installed or even by equipment installed later. Therefore, the effects of any such facilities must be considered in site selection and in determining whether a particular installation meets the FCC requirements. FCC OET Bulletin 65 provides materials to assist in making determinations if a given facility is compliant with the human exposure to RF radiation limits. Determining the compliance of transmitter sites of various complexities may be accomplished by means of computational methods. For more complex sites direct measurement of power density may be more expedient. Additional information on the topic of electromagnetic exposure is contained in the Motorola Standards and Guideline for Communications Sites of this equipment are urged to consult the listed reference material to assist in determining whether a given installation complies with the applicable limits. In general the following guidelines should be observed when working in or around radio transmitter sites:
publication. Persons responsible for installation
- All personnel should have electromagnetic energy awareness training.
- All personnel entering the site must be authorized.
- Obey all posted signs

The following description assumes such a conguration. Figures 5 shows an overall block diagram of the BR. Power is applied to the DC Power input located on the BR backplane. The DC Power input is connected if -48 VDC or batteries are used in the site. Power is applied to the BR by setting the Power Supply power switch to the ON position. Upon power-up, the BR performs self-diagnostic tests to ensure the integrity of the unit. These tests are primarily conned to the EBRC and include memory and Ethernet verication routines. After the self-diagnostic tests are complete, the BR reports any alarm conditions present on any of its modules to the site controller via Ethernet. Alarm conditions may also be veried locally using service computer and the STATUS port located on the front of the EBRC. The software resident in Flash Memory on the EBRC registers the BR with the site controller via Ethernet. Once registered, the BR software is downloaded via resident FLASH- or Ethernet and is executed from RAM. Operating parameters for the BR are included in this download. This software allows the BR to perform call processing functions. The BR operates in a TDMA (Time Division Multiple Access) mode. This mode, combined with voice compression techniques, provides an increased channel capacity ratio of as much as 6 to 1. Both the receive and transmit signals of the BR are divided into 6 individual time slots. Each receive slot has a corresponding transmit slot; this pair of slots comprises a logical RF channel. The BR uses diversity reception for increased coverage area and improved quality. The Receiver module within the BR contains up to three receivers. Two Receivers are used with two-branch diversity sites, and three Receivers are used with three-branch diversity sites. All Receivers within a given BR are programmed to the same receive frequency. The signals from each receiver are fed to the EBRC where a diversity combining algorithm is performed on the signals. The resultant signal is processed for error correction and then sent to the site controller via Ethernet with the appropriate control information regarding its destination. The transmit section of the BR is comprised of two separate FRUs, the Exciter and Power Amplier (PA). Several PA FRUs are available, covering different applications and power levels; these are individually discussed as applicable in later subsections. The Exciter processes the information to transmit from the EBRC in the proper modulation format. This low level signal is sent to the PA where it is amplied to the desired output power level. The PA is a continuous keyed linear amplier. A power control routine monitors the output power of the BR and adjusts it as necessary to maintain the proper output level. 10 68P80801E35-A 9/1/2001 EBTS System Manual - Vol 2 800/900/1500 MHz Base Radios Base Radio Overview FROM RFDS

The processor uses this bus to access non-volatile memory and SDRAM memory. Via memory mapping, the processor also uses this bus to control other BRC circuitry. The microprocessor uses its Chip Select capability to decode addresses and assert an output signal. The eight chip-select signals select non-volatile memory, SDRAM memory, input ports, output ports, and DSPs. The Host processor... Provides serial communications between the Host Microprocessor and other Base Radio modules. Provides condition signals necessary to access SDRAM. Accepts interrupt signals from EBRC circuits (such as DSPs). Organizes the interrupts, based on hardware-dened priority ranking. The Host supports several internal interrupts from its Communications Processor Module. These interrupts allow efcient use of peripheral interfaces. The Host supports 10 Mbps Ethernet/IEEE 802.3. Provides a 32-line data bus transfers data to and from EBRC SDRAM and other BRC circuitry. Buffers on this data bus allow transfers to and from non-volatile memory, general input and output ports and DSPs. Non-Volatile Memory Base Radio software resides in 2M x 32 bits of FLASH memory. The Host Microprocessor addresses the FLASH memory with 20 of the host address bus 32 lines. The host accesses FLASH data over the 32-line host data bus. A host-operated chip-select line provides control signals for these transactions. The FLASH contains the operating system and application code. The system stores application code in FLASH for fast recovery from reset conditions. Application code transfers from network or site controllers may occur in a 10 68P80801E35-A 9/1/2001 EBTS System Manual - Vol 2 Base Radio Controllers Enhanced Base Radio Controller background mode. Background mode transfers allow the station to remain operational during new code upgrades. The data that determines the station personality resides in a 32K x eight bit codeplug EEPROM. The microprocessor addresses the EEPROM with 15 of the host address bus 32 lines. The host accesses EEPROM data with eight of the data bus 32 lines. A host-operated chip-select line provides control signals for these transactions. During the manufacturing process, the factory programs the codeplugs default data. The BRC must download eld programming data from network and site controllers. This data includes operating frequencies and output power level. The station permits adjustment of many station parameters, but the station does not store these adjustments. Refer to the Software Commands chapter for additional information. Volatile Memory Each BRC contains 8MB x 32 bits of SDRAM. The BRC downloads station software code into SDRAM for station use. SDRAM also provides short-term storage for data generated and required during normal operation. SDRAM is volatile memory. A loss of power or system reset destroys SDRAM data. The system performs read and write operations over the Host Address and Data buses. These operations involve column and row select lines under control of the Host processors DRAM controller. The Host address bus and column row signals sequentially refresh SDRAM memory locations. Ethernet Interface The Host processors Communications Processor Module (CPM) provides the Local Area Network (LAN) Controller for the Ethernet Interface. The LAN function implements the CSMA/CD access method, which supports the IEEE 802.3 10Base2 standard. The LAN coprocessor supports all IEEE 802.3 Medium Access Control, including the following:
framing preamble generation stripping source address generation destination address checking The PCM LAN receives commands from the CPU. The Ethernet Serial Interface works directly with the CPM LAN to perform the following major functions:
10 MHz transmit clock generation (obtained by dividing the 20 MHz signal provided by on-board crystal) Manchester encoding/decoding of frames 68P80801E35-A 9/1/2001 11 Base Radio Controllers Enhanced Base Radio Controller EBTS System Manual - Vol 2 electrical interface to the Ethernet transceiver An isolation transformer provides high-voltage protection. The transformer also isolates the Ethernet Serial Interface (ESI) and the transceiver. The pulse transformer has the following characteristics:
Minimum inductance of 75 H 2000 V isolation between primary and secondary windings 1:1 Pulse Transformer The Coaxial Transceiver Interface (CTI) is a coaxial cable line driver and receiver for the Ethernet. CTI provides a 10Base2 connection via a coaxial connector on the board. This device minimizes the number of external components necessary for Ethernet operations. A DC/DC converter provides a constant voltage of -9 Vdc for the CTI from a 3.3 Vdc source. The CTI performs the following functions:
Receives and transmits data to the Ethernet coaxial connection Reports any collision that it detects on the coaxial connection Disables the transmitter when packets are longer than the legal length
(Jabber Timer) Digital Signal Processors The BRC includes two Receive Digital Signal Processors (RXDSPs) and a Transmit Digital Signal Processor (TXDSP). These DSPs and related circuitry process compressed station transmit and receive audio or data. The related circuitry includes the TDMA Infrastructure Support IC (TISIC) and the TISIC Interface Circuitry. The DSPs only accept input and output signals in digitized form. The RXDSP inputs are digitized receiver signals. The TXDSP outputs are digitized voice audio and data (modulation signals). These signals pass from the DSP to the Exciter portion of the EXBRC. DSPs communicate with the Microprocessor via an eight-bit, host data bus on the host processor side. For all DSPs, interrupts drive communication with the host. The RXDSP operates from an external 16.8 MHz clock, provided by the local station reference. The RXDSP internal operating clock signal is 150MHz, produced by an internal Phase-Locked Loop (PLL). The RXDSP accepts digitized signals from the TISIC device through the RxDSP parallel bus. The RXDSP supports a single carrier (single 3 branch receiver) digital data input. The RXDSP accesses its DSP program and signal-processing algorithms in 128k words of internal memory. The RXDSP communicates with the host bus on an 8-bit interface. Additionally, a serial control path connects the two RXDSPs and the TXDSP. The Synchronous Communications Interface (SCI) port facilitates this serial control path. 12 68P80801E35-A 9/1/2001 EBTS System Manual - Vol 2 Base Radio Controllers Enhanced Base Radio Controller For initialization and control purposes, the RXDSP connects to the TISIC device. The TXDSP operates at an external clock speed of 16.8 MHz, provided by the EBRC local station reference. The TXDSP internal operating clock is 150MHz, produced by an internal Phase Lock Loop (PLL). The TXDSP sends one carrier of digitized signal to the TISIC to reformat the date before sending it to the exciter. The exciter converts the digital signal to analog. The TXDSP contains its own, internal address and data memory. The TXDSP can store 128k words of DSP program and data memory. An eight-bit interface handles TXDSP-to-host bus communications. TISIC The TISIC controls internal DSP operations. This circuit provides the following functions:
For initialization and control, interfaces with the RXDSP via the DSP address and data buses. Accepts a 16.8 MHz signal from Station Reference Circuitry. Accepts a 5 MHz signal, modulated with one pulse per second (1 PPS) from the site reference. Demodulates the 1 PPS from the modulated 5 MHz signal Outputs a 1 PPS signal and a windowed version of this signal for network timing alignment. Outputs a 2.1 MHz reference signal used by the Exciter and Receiver(s). Generates 15 ms and 7.5 ms ticks. (These ticks synchronize to the 1 PPS time mark. The system decodes the time mark from the site reference. Then the system routes the reference to the TXDSP and RXDSP.) Provides a 4.8 MHz reference signal. This signal is used by the Exciter to clock data into the TRANLIN Accepts differential data from the Receiver(s) (Rx through Rx3) via the interface circuitry. Transmits serial control data to the Receiver(s) (Rx through Rx3) via the serial data bus. Accepts and formats differential data from the TXDSP for transmission to the Exciter via interface circuitry. Generates the Receiver SSI (RxSSI) frame sync interrupt for the RxDSP. Station Reference Circuitry The Station Reference Circuitry is a phase-locked loop (PLL). This PLL consists of a high-stability, Voltage-Controlled, Crystal Oscillator (VCXO) and a PLL IC. GPS output from the iSC connects to the 5 MHz/1 PPS BNC connector on the BR backplane. Wiring at this connector routes signals to EXBRC station reference circuitry. The PLL compares the 5 MHz reference frequency to the 16.8 MHz VCXO output. Then the PLL generates a DC correction voltage. The PLL applies this correction 68P80801E35-A 9/1/2001 13 Base Radio Controllers Enhanced Base Radio Controller EBTS System Manual - Vol 2 voltage to the VCO through an analog gate. The analog gate closes when three conditions coexist: (1) The 5 MHz tests stable. (2) The PLL IC is programmed. (3) Two PLL oscillator and reference signal output alignments occur. A loss in the 5MHz / 1PPS signal causes the control voltage enable switch to open. This complex PLL control allows the BR to maintain 16.5 MHz capability during short disconnects (of approximately one minute) of the 5 MHz / 1 PPS signal. (For example, during 5 MHz / 1 PPS cable maintenance work.) When the gate enables, the control voltage from the PLL can adjust the high-stability VCXO frequency. The adjustment can achieve a stability nearly equivalent to that of the external, 5 MHz frequency reference. The correction voltage from the PLL continuously adjusts the VXCO frequency. The VXCO outputs a 16.8 MHz clock signal. The circuit applies this clock signal to the receiver, and TISIC. The TISIC divides the 16.8 MHz signal by seven, and outputs a 2.1 MHz signal. This output signal then becomes the 2.1 MHz reference for the Exciter and Receiver(s). Input Ports One general-purpose input register provides for EBRC and station circuit input signals. The register has 16 input ports. The Host Data Bus conveys input register data to the Host Microprocessor. Typical inputs include 16.8 Station Reference Circuitry status outputs and reset status outputs. Output Ports Two general-purpose output registers distribute control signals from the Host Microprocessor to the BRC and station circuitry. One register has 32 output ports and the other register has 8 output ports. Control signal distribution occurs over the backplane. The Host Data Bus drives the output ports latched outputs. Typical control signals include front-panel LED signals and SPI peripheral enable and address lines. Remote Station Shutdown The EBRC contains power supply shutdown circuitry. This circuitry can send a shutdown pulse to the Base Radio Power Supply. BRC software generates the shutdown control pulse. After receiving a shutdown pulse, the power supply turns off BR power. Shut down power sources include 3.3, 5.1, 28.6 and 14.2 Vdc sources throughout the BR. Due to charges retained by BR storage elements, power supply voltages may not reach zero. The shutdown only assures that the host processor enters a power-on-reset state. A remote site uses the shutdown function to perform a hard reset of all BR modules. 14 68P80801E35-A 9/1/2001 800/900/1500 MHz Base Radios Base Radio Controller 12 LED CONTROL LINES HOST LATCH P0 OUT BASE RADIO POWER SUPPLY EXCITER PA CTL RX1 RX2 R3 FRONT PANEL LEDS 5MHZ_1PPS BASE RADIO INPUT G A T I N G SYNTHESIZER IC / CIRCUITRY PHASE DETECTION/

The Low Noise Exciter module consists of a printed circuit board, a slide in housing, and associated hardware. The Low Noise Exciter connects to the Base Radio backplane through a 96-pin DIN connector and two blindmate RF connectors. Two Torx screws on the front of the Exciter secure it to the chassis. There are no controls or indicators on the Exciter. Specications of the transmitter circuitry, including the Exciter and PAs, are provided in the Base Radio section of the manual.

Table 3 Exciter Circuitry Circuit Low Noise IC Memory & A/D Converter Frequency Synthesizer Circuitry Description Up-converts baseband data to the transmit frequency Down-converts the PA feedback signal to baseband Uses a baseband Cartesian feedback loop system, necessary to obtain linearity from the transmitter and avoid splattering power into adjacent channels Performs training functions for proper linearization of the transmitter Serves as the main interface between the synthesizer, Tranlin IC, A/D, and EEPROM on the Exciter, and the BRC via the SPI bus Consists of a phase-locked loop and VCO Provides a LO signal to the Low Noise IC for the second up-conversion and rst down-conversion of the feedback signal from the PA 970 MHz VCO (800 MHz BR) Provides a LO signal to the Low Noise IC, for up-conversion to the transmit frequency 90.3 MHz VCO (800 MHz BR) Regulator Circuitry Provides a LO signal to Low Noise IC, for the up-conversion and for the down-conversion of the feedback signal. The mixed output becomes the LO signal for Transmit signal up- and down- conversion Provides a regulated voltage to various ICs and RF devices located on the Exciter Linear RF amplier Stages Amplies the RF signal from the Exciter IC to an appropriate level for input to the PA Memory Circuitry The memory circuitry is loaded on an EEPROM on the Exciter. The EBRC performs memory read and write operations via the SPI bus. Information stored in this memory device includes the kit number, revision number, module-specic scaling, and correction factors, operations, parameters, and free-form information
(scratch pad) kit number A/D Converter Circuitry Analog signals from various areas throughout the Exciter board enter the A/D converter (A/DC). The A/DC converts these analog signals to digital form. Upon request of the BRC, A/DC output signals enter the BRC via SPI lines. The Controller periodically monitors all signals. Some of the monitored signals include amplier bias and synthesizer signals. 8 68P80801E35-A 9/1/2001 EBTS System Manual - Vol 2 Base Radio Exciter Low Noise 800 MHz Exciter LNODCT IC Circuitry The LNODCT IC (Low Noise Offset Direct Conversion Transmit IC) is a main interface between the Exciter and BRC. The BRCs Digital Signal Processor (DSP) sends digitized signals (baseband data) to the Exciter over the DSP data bus. The differential data clock signal serves as a 2.4 MHz reference signal to the LNODCT ICs internal synthesizer. The LNODCT compares the reference signal with the outputs of Voltage Controlled Oscillators (VCOs). The LNODCT might sense that a VCOs output is out of phase or off-frequency. If so, then the LNODCT sends correction pulses to the VCO. The pulses adjust VCO output, thereby matching phase and frequency with the reference. The LNODCT IC up-converts baseband data from the EBRC to the transmit frequency. The LNODCT IC also down-converts the Transmit signal from the Power Amplier to baseband data for cartesian feedback linearization. The EBRC uses the Serial Peripheral Interface (SPI) bus to communicate with the LNODCT IC. The SPI bus serves as a general purpose, bi-directional, serial link between the EBRC and other Base Radio modules, including the Exciter. The SPI carries control and operational data signals to and from Exciter circuits. Synthesizer Circuitry The synthesizer circuit consists of the Phase-Locked Loop (PLL) IC and associated circuitry. This circuits controls the 970 MHz VCO signal. An internal phase detector generates a logic pulse. This pulse is proportional to the phase or frequency difference between the reference frequency and loop pulse signal. The charge pump circuit generates a correction signal. The correction signal moves up or down in response to phase detector output pulses. The correction signal passes through the low-pass loop lter. The signal then enters the 970 MHz Voltage Controlled Oscillator (VCO) circuit. 970 MHz Voltage Controlled Oscillator (VCO) For proper operation, the VCO requires a very low-noise, DC supply voltage. An ultra low-pass lter prepares the necessary low-noise voltage and drives the oscillator. A portion of the oscillator output signal enters the synthesizer circuitry. The circuitry uses this feedback signal to generate correction pulses. The 970 MHz VCO output mixes with the 90.3 MHz VCO output. The result is a Local Oscillator [LO) signal for the LNODCT IC. The LNODCT uses this LO signal to up-convert the programmed transmit frequency. The LNODCT also uses the LO signal to down-convert the PA feedback signal. 68P80801E35-A 9/1/2001 9 Base Radio Exciter Low Noise 800 MHz Exciter EBTS System Manual - Vol 2 90.3 MHz Voltage Controlled Oscillator (VCO) The synthesizer within the LNODCT IC sets the 90.3 MHz signal. The 90.3 MHz VCO provides a LO signal to the LNODCT IC. The LNODCT uses this signal in up-converting and down-converting the feedback signal. Regulator Circuitry The voltage regulators generate three regulated voltages: +3 Vdc, +5 Vdc and
+11.7 Vdc. The regulators obtain input voltages from the +3.3 Vdc and +14.2 Vdc backplane voltages. The regulated voltages power various ICs and RF devices in the Exciter. Linear RF Amplier Stages The linear RF ampliers boost the RF signal from the LNODCT IC. The RF Amplier generates an appropriate signal level to drive the PA. 10 68P80801E35-A 9/1/2001 LNODCT IC CIRCUITRY EXCITER IC CIRCUITRY 970 MHZ VCO CIRCUITRY EBTS System Manual - Vol 2 RF FEEDBACK FROM PA MODULE DIFFERENTIAL 800/900/1500 MHz Base Radios Exciter

DC/Metering Board (Non-QUAD PA) The DC/Metering Board provides the interface between the PA and the Base Radio backplane. The preamplied/modulated RF signal is input directly from the Exciter via the Base Radio backplane. The RF input signal is applied to the input of the Linear Driver Module (LDM). The RF feedback signal is fed back to the Exciter, where it is monitored for errors. The primary function of the DC/Metering Boards is to monitor proper operation of the PA. This information is forwarded to the Base Radio Controller (BRC) via the SPI bus. The alarms diagnostic points monitored by the BRC on the PA include the following:
Forward power Reected power PA temperature sense Fan Sensor 68P80801E35-A 9/1/2001 9 Power Amplifier (PA) PA Theory of Operation EBTS System Manual - Vol 2 DC/Metering Board (QUAD PA Only) The DC/Metering Board in the QUAD Radio serves the same function as it does in other radios. However, its circuitry is modied for compatibility with the QUAD Station. As a result, its logic circuitry is operated at 3.3 VDC. In addition to the functions listed for non-QUAD versions above, the following meter points are ported to the SPI bus:
A and B Currents Thermistor (for PA temperature sensing circuit on the DC/Metering Board) Linear Driver Module 40W-800 MHz, 70W-800 MHZ and 800 MHZ QUAD PAs The Linear Driver Module (LDM) amplies the low-level RF signal from the Exciter. The LDM consists of a two-stage cascaded Class AB amplier, with the nal stage in a parallel conguration. See Table 2 for the approximate input and output levels of the various LDMs. The LDM output is fed to the RF Splitter/DC Distribution Board via an Interconnect Board. 900 MHz PA The Linear Driver Module (LDM) amplies the low-level RF signal from the Exciter. The LDM consists of a three-stage, cascaded, Class AB amplier, with the rst two stages congured as distributed ampliers and the nal stage in a push-pull conguration. This output is fed directly to the RF Splitter/DC Distribution Board. See Table 2 for the approximate input and output power of the 900 MHz LDM. The LDM output is fed to the RF Splitter/DC Distribution Board via the Interconnect Board. 1500 MHz PA The Linear Driver Module (LDM) takes the low level RF signal and amplies it. The LDM consists of a four stage, cascaded, Class AB amplier, with the nal stage congured in push-pull conguration. This output is fed directly to the RF Splitter/DC Distribution Board. See Table 2 for the approximate input and output power of the 1500 MHz LDM. 10 68P80801E35-A 9/1/2001 EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation 900 QUAD PA The Linear Driver Module (LDM) amplies the low-level RF signal from the Exciter. The LDM consists of a three stage, cascaded, Class AB amplier, with the nal stage in a parallel conguration. See Table 2 for the approximate input and output power of the 900 MHz QUAD LDM. The LDM Output is fed to the RF Splitter/DC Distribution Board via the Interconnect Board. Interconnect Board (40W-800 MHz, 70W-800 MHz , 800 MHz QUAD and 900 MHz QUAD) The output of the LDM is applied to the Interconnect Board, which provides an RF connection to the RF Splitter/DC Distribution Board. As a separate function, area on the Interconnect Board serves as a convenient mounting location for electrolytic capacitors used for ltering the +28 VDC supply. RF Splitter/DC Distribution Board 40W-800 MHz, 70W-800 MHz, 800 MHz QUAD and 900 MHz QUAD The RF Splitter portion of this board accepts the amplied signal from the LDM
(via the Interconnect Board). The primary function of this circuit is to split the RF signal into drive signals for the LFMs. In the 40W-800 MHz PA, this circuit splits the drive signal into three separate paths to be applied to the three LFMs, where the signals will be amplied further. In the 70W-800 MHz, 800 MHz QUAD and 900 MHZ QUAD PAs, this circuit splits the drive signal into six separate paths to be applied to the six LFMs, where the signals will be amplied further. The DC Distribution portion of this board interfaces directly with the DC/
Metering Board to route DC power to the LFMs. 900 MHz and 1500 MHz The RF Splitter portion of this board accepts the amplied signal from the LDM. The primary function of this circuit is to split the RF signal into two separate paths. These two outputs are fed directly to two separate Linear Final modules where the RF signals will be amplied further. The DC Distribution portion of this board interfaces directly with the DC/
Metering Board to route DC power to the LFMs. Linear Final Modules 40W-800 MHz, 70W-800 MHz, 800 MHz QUAD and 900 MHz QUAD The RF Splitter output signals are applied directly into the LFMs for nal amplication. Each LFM contains a coupler that splits the LFM input signal and feeds the parallel Class AB ampliers that amplify the RF signals. 68P80801E35-A 9/1/2001 11 Power Amplifier (PA) PA Theory of Operation EBTS System Manual - Vol 2 In the 40W PA, the amplied signals are then combined on the LFM and sent directly to the RF Interconnect Board. In the 70W PA, the amplied signals are then combined on the LFM and sent directly to the Combiner Board. See Table 2 for the approximate total summed output powers of the various LFMs, before output losses. 900 MHz PA The RF signals from the outputs of the RF Splitter are applied directly into the Linear Final Module (LFM) for nal amplication. Each LFM contains a branchline coupler that splits the LFMs input signal and feeds the dual Class AB push-pull ampliers that amplify the RF signals. The amplied signals are then combined on the LFM and sent directly to the RF Combiner circuit for nal distribution. See Table 2 for the approximate total summed output power of the 900 MHz LFMs, before output losses. 1500 MHz PA The two RF signals from the outputs of the RF Splitter are input directly into the Linear Final Module (LFM) for nal amplication. Each LFM contains a branchline coupler that splits the LFMs input signal and feeds the dual Class AB push-pull ampliers that amplify the RF signals. The amplied signals are then combined on the LFM , via a branchline coupler, and sent directly to the RF Combiner circuit for nal distribution. See Table 2 for the approximate total summed output power of the 1500 MHz LFMs, before output losses. The current drains of the 1500 MHz LFMs are monitored by the A/D converter on the DC/Metering board. A voltage signal representative of the LFM current drain is sent to the BRC. A Power Amplier alarm is generated if the signal is outside of either the upper or lower limits. RF Interconnect Board (40W- 800 MHz PA Only) The RF Interconnect Board consists of transmission line paths which route the three output signals from the LFMs to the three inputs of the RF Combiner/
Peripheral Module. Combiner Board (40W- 800 MHz, 70W- 800 MHz, 800 MHz QUAD and 900 MHz QUAD PAs) The Combiner Board combines pairs of signals into single signals, thereby combining the six signals from the LDMs into three signals. The resulting three signals are applied to the RF Combiner/Peripheral Module. RF Combiner/Peripheral Module (40- 800 MHz, 70W- 800 MHz PAs) This module consists of two portions: an RF combiner and a peripheral module. The RF Combiner portion of the module combines the three RF signals from the RF Interconnect Board (40W- 800 MHz PA) or the Combiner Board (70W- 800 MHz PA) into a single signal using a Wilkinson coupler arrangement. 12 68P80801E35-A 9/1/2001 EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation Following the combiner circuit, the single combined RF signal is then passed through a directional coupler which derives a signal sample of the LFM RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/Metering Board, as a feedback signal. Following the coupler, the power output signal is passed through a single stage circulator, which protects the PA in the event of high reected power. The peripheral portion of the module provides a power monitor circuit that monitors the forward and reected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals representative of the forward and reected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within parameters, the BRC will issue a warning to the site controller which, in turn, will shut down the Exciter if required. Reected power is monitored in the same manner. The BRC uses the reected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is determined to be excessive, the forward power is rolled back. If it is extremely excessive, the BRC issues a shut-down command to the Exciter. A thermistor is located on the RF Combiner/Peripheral module to monitor the operating temperature of the PA. The thermistor signal indicating excessive temperature is applied to the A/D converter and then sent to the BRC. The BRC rolls back forward power if the monitored temperature is excessive. 900 MHz PA This module consists of two parts: an RF combiner and a peripheral module. The RF combiner combines the two RF signals from each LDM into a single signal, using a branchline coupler arrangement. Then, the RF signal passes through a directional coupler which derives a signal sample of the LFMs RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/
Metering Board, as a feedback signal, thereby allowing the Exciter to accordingly adjust signal drive. Following the coupler, the power output signal is passed through a circulator, which protects the PA in the event of high reected power. A power monitor circuit monitors the forward and reected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals representative of the forward and reected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within parameters, the BRC will issue a warning to the site controller which, in turn, will shut down the Exciter if required. Reected power is monitored in the same manner. The BRC uses the reected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is determined to be excessive, the forward power is rolled back. If it is extremely excessive, the BRC issues a shut-down command to the Exciter. A thermistor is located on the RF Combiner/Peripheral module to monitor the operating temperature of the PA. A voltage representative of the monitored 68P80801E35-A 9/1/2001 13 Power Amplifier (PA) PA Theory of Operation EBTS System Manual - Vol 2 temperature is sent from the A/D converter to the BRC. The BRC rolls back forward power if the monitored temperature is excessive. 14 68P80801E35-A 9/1/2001 EBTS System Manual - Vol 2 Power Amplifier (PA) PA Theory of Operation 1500 MHz Both LFM outputs are input into this module where they are combined, with a branchline coupler, for a single output signal. The RF signal is rst coupled to the Exciter module, via the DC/Metering Board, so that it can be monitored. The RF output signal is then passed through a circulator that acts as a protection device for the PA in the event of reected power. A power monitor circuit monitors the forward and reected power of the output signal. This circuit provides the A/D converter on the DC/Metering board with an input signal representative of the forward or reected power levels. For forward power, a signal representative of the measured value is sent to the BRC module via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. The programmed forward power is set through the use of MMI commands. If the level is not within certain parameters, the BRC will issue a warning to the site controller and may shut-down the Exciter module. Reected power is monitored in the same manner except that the BRC determines an acceptable reected power level. The BRC calculates the reected power through an algorithm stored in memory. If the reected power is determined to be excessive, the forward power is rolled back. If the reected power level is extremely excessive, the BRC will issues a shut-down command to the Exciter module. A thermistor is located on the RF Combiner/Peripheral module to monitor the operating temperature of the Power Amplier. A voltage representative of the monitored temperature is sent from the A/D converter to the BRC. The BRC issues a cut-back command to the Exciter module if the monitored temperature is greater than 121 F (85 C). RF Combiner/Peripheral Module (800 MHz QUAD and 900 MHz QUAD) This module consists of two parts: an RF combiner and a Peripheral module. The RF combiner combines three RF signals from the Combiner Board into a single signal using a Wilkinson coupler arrangement. Following the combiner circuit, the single combined RF signal is then passed through a directional coupler, which derives a signal sample of the LFM RF power output. Via the coupler, a sample of the RF output signal is fed to the Exciter, via the DC/Metering Board, as a feedback signal. Following the coupler, the power output signal is passed through a dual stage circulator, which protects the PA in the event of high reected power. The Peripheral module provides a power monitor circuit that monitors the forward and reected power of the output signal. This circuit furnishes the A/D converter on the DC/Metering Board with input signals, representative of the forward and reected power levels. For forward power, a signal representative of the measured value is sent to the BRC via the SPI bus. The BRC determines if this level is within tolerance of the programmed forward power level. If the level is not within tolerance, the BRC will issue a warning to the site controller, which, in turn, will shut down the Exciter, if required. 68P80801E35-A 9/1/2001 15 Power Amplifier (PA) EBTS System Manual - Vol 2 Reected power is monitored in the same manner. The BRC uses the reected power to calculate the voltage standing wave ratio (VSWR). If the VSWR is calculated as excessive, forward power is rolled back. If the VSWR calculation is exceedingly out of tolerance, the BRC issues a shut-down command to the Exciter. NOTE The Thermistor that monitors the operating temperature of the 800 MHZ QUAD and 900 MHz QUAD PAs is located on the DC/Metering Board Fan Module The PA contains a fan assembly to maintain normal operating temperature through the use of a cool air intake. The fan assembly consists of three individual fans in which airow is directed across the PA heatsink. The current draw of the fans is monitored by the DC/Metering Board. A voltage representative of the current draw is monitored by the BRC. The BRC ags the iSC if an alarm is triggered. The PA LED on the front panel of the BRC also lights, however the PA does not shut down due to a fan failure alone.

For example, the combined length of the -48 Vdc (hot) lead and the DC return lead equals the cable loop length. This would mean that a cabinet that needs 16 feet of wire between the batteries and Power Supply Rack has a total loop length of 32 feet. Determining Battery System Wire Size The wire size for the connection between the batteries and the Power Supply Rack is determined by the required wire length and the maximum allowable voltage drop. The voltage drop in the loop must be kept to below 200 mV. The wire selected should be UL approved and contain a high number of strands for exibility. For a standard conguration, the Power Supply rack is located directly adjacent to the batteries with a cable loop length of 20 feet or less, which requires the use of a 4/0 wire. Table 3 shows recommended wire sizes for various loop lengths. Larger wire sizes may be used if the recommended sizes are not available. The recommended wire sizes are large enough to allow site expansion to a fully loaded site. Table 3 Battery System Wire Size Loop Length Wire size 20 feet 30 feet 45 feet 4/0 (or 250 MCM) 350 MCM 500 MCM Selecting Battery System Lugs Depending on the wire size used and the manufacturer of the Batteries, different wire lugs are crimped onto the power cable ends. After the wire size has been determined from Table 3, verify the manufacturer of the Batteries (Dynasty or Absolyte ). Two different battery systems are offered with the EBTS. The Dynasty system is a low to medium capacity, eld expandable system supplied for smaller sites or sites with minimal backup hour requirements. This system is custom designed to Motorola specications. The Dynasty system is manufactured by Johnson Controls:
