INSTALLATION Section 2 2-1. INTRODUCTION This section contains installation recommendations, unpacking, installation instructions for the multicarrier PCS amplifier. Carefully read all material in this section prior to equipment unpacking or installation. Also read and review the operating procedures in Section 3 prior to installing the equipment. It is important that the licensee perform these tasks correctly and in good faith. If applicable, carefully read Parts 73 and 74 of the Federal Communications Commission (FCC) rules to determine how they apply to your installation. DON'T TAKE CHANCES WITH YOUR LICENSE. inspection, and 2-2. ELECTRICAL SERVICE RECOMMENDATIONS Powerwave Technologies recommends that proper AC line conditioning and surge suppression be provided on the primary AC input to the +27 Vdc power source. All electrical service should be installed in accordance with the National Electrical Code, any applicable state or local codes, and good engineering practice. Special consideration should be given to lightning protection of all systems in view of the vulnerability of most transmitter sites to lightning. Lightning arrestors are recommended in the service entrance. Straight, short ground runs are recommended. The electrical service must be well grounded. Each amplifier system should have its own circuit breaker, so a failure in one does not shut off the whole installation. Circuit breakers should be thermal type, capable of handling the anticipated inrush current, in a load center with a master switch. 2-3. UNPACKING AND INSPECTION This equipment has been operated, tested and calibrated at the factory. Only in the event of severe shocks or other mistreatment should any substantial readjustment be required. Carefully open the container(s) and remove the amplifier module(s). Retain all packing material that can be reassembled in the event that the unit must be returned to the factory. CAUTION Exercise care during inspection caused by rough or careless handling. in handling equipment to prevent damage Visually inspect the amplifier module for damage that may have occurred during shipment. Check for evidence of water damage, bent or warped chassis, loose screws or nuts, or extraneous packing material in the connector or fans. Inspect the rear panel connector for bent connector pins. If the equipment is damaged, a claim should be filed with the carrier once the extent of any damage is assessed. We cannot stress too strongly the importance of IMMEDIATE careful inspection of the equipment and the subsequent IMMEDIATE filing of the necessary claims against the carrier if necessary. If possible, inspect the equipment in the presence of the delivery person. If the equipment is damaged, the carrier is your first area of recourse. If the equipment is damaged and must be returned to the factory, write or phone for a return authorization. Powerwave may not accept returns without a return authorization. Claims for loss or damage may not be withheld from any payment to Powerwave, nor may any payment due be withheld pending the outcome thereof. WE CANNOT GUARANTEE THE FREIGHT CARRIER'S PERFORMANCE. 044-05077 Rev. A 2-1 2-4.

INITIAL START-UP AND OPERATING PROCEDURES The amplifier module has two operating controls, both located on the front face of the module: the power ON - OFF switch and the RF ON - ON/OFF/RESET switch. To perform the initial start-up, proceed as follows:

1. Double check to ensure that all input and output cables are properly connected. CAUTION Before applying power, make sure that the input and output of the amplifier are properly terminated at 50 ohms. Do not operate the amplifier without a load attached. Refer to table 1-2 for input power requirements. Excessive input power may damage the am-

plifier The output coaxial cable between the amplifier and the antenna must be 50 ohm coaxial cable. Use of any other cable will distort the output. NOTE 2. Verify that the amplifier front panel switches are in the OFF position. 3. Turn on supply that provides +27 Vdc to the amplifier system. Do not apply an RF signal to the amplifier system 4. Place the ON - OFF circuit breaker on the amplifier in the ON position. Visually check the indicators on the amplifier module, and verify that the following indicators are on:

PRINCIPLES OF OPERATION Section 4 4-1. INTRODUCTION This section contains a functional description of the multicarrier cellular amplifier. 4-2. RF INPUT SIGNAL The maximum input power for all carrier frequencies should not exceed the limits specified in table 1-2. For proper amplifier loop balance, the out of band components of the input signals should not exceed -40 dBc. The input VSWR should be 2:1 maximum (or better). 4-3. RF OUTPUT LOAD The load impedance should be as good as possible (1.5:1 or better) in the working band for good power transfer to the load. If the amplifier is operated into a filter, it will maintain its distortion characteristics outside the signal band even if the VSWR is infinite, provided the reflected power does not exceed one watt. A parasitic signal of less than one watt incident on the output will not cause distortion at a higher level than the normal forward distortion (i.e. -65 dBc). 4-4. SYSTEM FUNCTIONAL DESCRIPTION The G3S-1900-80 amplifier is a linear, feed-forward power amplifier that operates in the 60 MHz frequency band from 1930 MHz to 1990 MHz. It is designed to operate in a maximum of two continuous frequency blocks in the PCS band or an instantaneous bandwidth of 20 MHz. A typical two-module system is shown in figure 4-1. The power output specification is listed in table 1-2. Each amplifier is a self-contained plug-in module and is functionally independent of the other amplifier module. The amplifier modules are designed for parallel operation to achieve high peak power output, and for redundancy in unmanned remote locations. Each amplifier in the system can simultaneously transmit multiple carrier frequencies, at an average total power output of 70 watts

(one amplifier module in a subrack unit) to 140 watts (two amplifier modules), with -65 dBc third order intermodulation distortion (IMD). The output from each amplifier is an amplified composite signal of approximately 80 watts before combiner losses. All phase and gain corrections are performed on the signal(s) in the individual amplifier modules. In a two-module system, the amplifier outputs are fed to a power combiner and combined to form a composite RF output of up to 140 watts. Each amplifier module has an alarm and display board that monitors the amplifier performance. If a failure or fault occurs in an amplifier module, it is displayed on the individual amplifier front panel. 4-5. G3S-1900-80 AMPLIFIER MODULE The amplifier module, figure 4-2, has an average output of 80 watts power (800 watts peak power) with intermodulation products suppressed to better than -65 dBc below carrier levels. The amplifier provides an amplified output signal with constant gain and phase by adding approximately 25 dB of distortion cancellation on the output signal. Constant gain and phase is maintained by continuously comparing active paths with passive references, and correcting for small variations through the RF feedback controls. All gain and phase variations, for example those due to temperature, are reduced to the passive reference variations. The amplifier module is comprised of:

RS485/RS232 J1 J7 J8 2X3 2X3 DB9 DB9 DB9 Figure 4-1. G3S-1900-80 Two-Module Amplifier System The main amplifier employs class AB amplification for maximum efficiency. The error amplifier and feed forward loops are employed to correct signal nonlinearities introduced by the class AB main amplifier. The error amplifier operates in class AB mode. The RF input signals are amplified by a preamp and coupled to an attenuator and phase shifter in the first feed-forward loop. The main signal is phase shifted by 180 degrees and amplified in the premain amplifier. The output from the premain amplifier is fed to the class AB main amplifier. The output from the main amplifier is typically 100 watts. The signal is output to several couplers and a delay line. The signal output from the main amplifier is sampled using a coupler, and the sample signal is combined with the main input signal and input to the second feed-forward loop. The error signal is attenuated, phase shifted 180 degrees, then fed to the error amplifier where it is amplified to a level identical to the sampled output from the main amplifier. The output from the error amplifier is then coupled back and added to the output from the main amplifier. The control loops continuously make adjustments to cancel out any distortion in the final output signals. 044-05077 Rev. A 4-2 The primary function of the first loop is to provide an error signal for the second loop. The primary function of the second loop is to amplify the error signal to cancel out spurious products developed in the main amplifier. The input signal is amplified by a preamplifier and fed to a coupler and delay line. The signal from the coupler is fed to the attenuator and phase shifter in the 1st loop. The first loop control section phase shifts the main input signals by 180 degrees and constantly monitors the output for correct phase and gain. Figure 4-2. G3S-1900-80 Power Amplifier Module Functional Block Diagram The 2nd loop control section obtains a sample of the distortion added to the output signals by the main amplifiers, phase shifts the signals by 180 degrees, then feeds it to the error amplifier. There it is amplified to the same power level as the input sample and coupled on to the main output signal. The final output is monitored by the 2nd loop and adjusted to ensure that the signal distortion and IMD on the final output is canceled out. 4-5.1. MAIN AMPLIFIER The input and output of the amplifier employ two-stage, class AB amplifiers, which provide approximately 25 dB of gain in the 60 MHz frequency band from 1930 to 1990 MHz. The amplifier operates on +27 Vdc, and is mounted directly on a heat sink, which is temperature monitored by a thermal sensor. If the heat sink temperature exceeds 85 C, a high temperature fault occurs. The alarm logic controls the transistor bias voltage, which shuts down the amplifier. 4-5.2. ERROR AMPLIFIER The main function of the error amplifier is to sample and amplify the signal distortion level generated by the main amplifier, to a level that cancels out the distortion and IMD when the error signal is coupled onto the main signal at the amplifier output. The error amplifier is a balanced multistage, class AB amplifier, has 75 dB of gain, and produces up to a 65-watt output. The amplifier operates on +27 Vdc and is mounted directly on a heat sink. 4-5.3. AMPLIFIER MONITORING In the main and error amplifier modules, all normal variations are automatically compensated for by the feedforward loop control. However, when large variations occur beyond the adjustment 044-05077 Rev. A 4-3 range of the loop control, a loop fault will occur. The alarms are displayed on the front panel indicators and output via a 21-pin connector on the rear of the module to the subrack summary board for subsequent remote monitoring via the ALARMS connector. Refer to paragraph 2-5.1 as well as figure 2-2 and table 2-1 for a description of the ALARMS connector. 4-5.4. AMPLIFIER MODULE COOLING Although each amplifier module contains its own heat sink, it is cooled with forced air. Four fans are used for forced air cooling and redundancy. The fans, located on the front and rear of the amplifier module, draw air in through the front of the amplifier and exhaust hot air out the back of the module. The fans are field replaceable. 4-6. POWER DISTRIBUTION Primary DC power for the system is provided by the host system to the MCR2200 Series subrack. The subrack supplies each amplifier module with +27 Vdc directly and via the RF power splitter/combiner. The amplifier module has a DC/DC converter that converts the +27 Vdc to +15 Vdc, +5 Vdc and -5 Vdc. 4-7. INTERMODULATION The G3S-1900-80 amplifier is designed to deliver a 80-watt composite average power, multicarrier signal, occupying a bandwidth less than or equal to 20 MHz, in the bandwidth from 1930 to 1990 MHz. The maximum average power for linear operation, and thus the amplifier efficiency, will depend on the type of signal amplified. 4-7.1 TWO TONE INTERMODULATION When measured with two equal CW tones spaced anywhere from 30 kHz to 20 MHz apart, and at any power level up to the average power, the third order intermodulation products will be below

-65 dBc 4-7.2 MULTITONE INTERMODULATION Adding more tones to the signal will lower individual intermodulation products. If the frequencies are not equally spaced, the level of intermodulation products gets very low. When the frequencies are equally spaced, those products fall on top of each other on the same frequency grid. The average power of all intermodulation beats falling on the same frequency is called the composite intermodulation; it is -65 dBc or better. 4-8. ALARMS The presence of several plug-in amplifier alarms can be detected at the DC and logic connector on the amplifier rear panel. Refer to table 2-1 and figure 2-2 for a description of the connector. 044-05077 Rev. A 4-4

GENERAL DESCRIPTION Section 1 1-1. INTRODUCTION This manual contains information and procedures for installation, operation, and maintenance of Powerwaves G3S-1900-80 multicarrier PCS amplifier. The manual is organized into six sections as follows:

Section 1. General Description Section 2. Installation Section 3. Operating Instructions Section 4. Principles of Operation Section 5. Maintenance Section 6. Troubleshooting 1-2. GENERAL DESCRIPTION The G3S-1900-80 (see figure 1-1) is a linear, feed-forward power amplifier that operates in the 60 MHz frequency band from 1930 MHz to 1990 MHz. It is designed to operate in a maximum of two continuous frequency blocks in the PCS band or a total instantaneous bandwidth of 20 MHz. The amplifier can simultaneously transmit multiple frequencies, with better than -65 dBc third order intermodulation distortion (IMD). It is designed for use in an amplifier system that is modular in design, and is ideally suited for use in GSM/TDMA/CDMA base stations. When used in a subrack employing two G3S-1900-80 amplifiers, the system offers up to 140 watts output. The plug-in Model G3S-1900-80 amplifier modules can each provide 80 watts of power and function completely independently of each other. The amplifier modules are designed for parallel operation to produce high peak power output and backup redundancy for remote applications. All solid-state, the system is designed to provide trouble-free operation with minimum maintenance. The system's modular construction and unique and highly effective LED-based operational status and fault indicators help minimize downtime. The turn-on and turn-off sequences of voltages are fully automatic, as is overload protection and recycling. Inadvertent operator damage from front panel manipulation is virtually impossible. Each amplifier module has a status connector that allows the host system to monitor the amplifier module performance. The front panel of each amplifier module has unit level status/fault indicators and an RF on/off/reset switch. Primary power for the amplifier is +27 Vdc. Cooling for each plug-in amplifier module is provided by four fans, two mounted on the front and two on the rear of the module. The fans draw outside air through the front of the module and exhaust hot air out through the rear of the module. 1-3. FUNCTIONAL AND PHYSICAL SPECIFICATIONS Functional and physical specifications for the amplifier are listed in table 1-2. 1-4. EQUIPMENT CHANGES Powerwave Technologies, Inc. reserves the right to make minor changes to the equipment, including but not necessarily limited to component substitution and circuitry changes. Changes that impact this manual may subsequently be incorporated in a later revision of this manual. 044-05077 Rev. A 1-1 1-5.
