TM0054 NOTE IMPORTANT RATING INFORMATION Manufacturers rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced as per Table 1-4, especially where the output signal is re-radiated and can cause interference to adjacent band users. This output power reduction is to be achieved by reduction of input power or by gain reduction and not by an attenuator at the output of the device. Rated Power Output for Linear Operation TABLE 1-4 The total composite output power in multiple tone or wideband signals shall NOT exceed the following level or else it may result in improper operation of the device and cause interference. The composite output power rating is defined as the total average RMS output power of all inband signals. The unit should be operated at or below this level to ensure linear operation with low distortion. This holds true for any number of carriers with total average power adding up to the composite output power rating listed in the table below. Parameter Base Transmit (Downlink) Total Power:

THEORY OF OPERATION 2.1 THEORY OF OPERATION The R280 is a bidirectional repeater, providing a maximum of approximately 70 dB gain in both the uplink and downlink frequency bands. The block diagram of the R280 is shown in Figure 2-1. The unit is composed of IF conversion modules, amplifiers, and diplexers as well as a control module. Please refer to Figure 2-1. The downlink signal enters the unit via the Base Antenna connector. After the signal passes through the high band port of the diplexer within the Uplink Amp module, the signal is split and then fed into the 2 Downlink IF Conversion Modules. The modules use IF conversion to provide sharp filtering of downlink signals in order to reject out of band signals. The conversion modules have a typical gain of 50 dB. After the 2 downlink signals are combined within the Downlink Amp module, they are fed into the downlink amp and then into the high band port of the diplexer within the Downlink Amp module. The downlink signal then appears at the Distribution Antenna connector. The unit's operation in the uplink band is similar to the downlink band discussed in the previous paragraph but uses the Uplink IF Conversion Modules along with the uplink amp in the Uplink Amp module and the low band ports of the diplexers to provide gain from the Distribution Antenna to the Base Antenna. The Controller module sets the center frequency of the IF conversion modules. When the unit is first switched on, the controller module sends a signal to set the center frequency of the IF conversion modules. It then enables the modules once the PLLs have locked and stabilized to the specific band of operation. The controller is pre-
programmed at the factory with the correct customer frequencies. The controller module also contains the attenuation control. The rotary switch on the module adjusts the attenuation setting of both the uplink and downlink IF conversion modules to the value indicated by the switch knob pointer. The attenuators can be set over the range of 0 to 30 dB in 2 dB steps. Changing the setting has a immediate affect on the attenuators. 2-1 P.G. TM0054 External DC power is fed to the unit through the DIN power jack on the bottom of the unit. Power is fed from this module to the Uplink Amp, Downlink Amp and Controller modules. The IF conversion modules obtain their power through the Controller module. The interface module contains two LED indicators. The red LED indicates a PLL unlock condition and may illuminate briefly when the unit is first switched on while the PLLs are locking and the modules are disabled. Under normal operation, only the green LED will be on. Both normally open and normally closed alarm relay contact terminals are provided on the interface module for connection to external remote monitoring equipment. An alarm condition exists for PLL unlock condition or when unit is not powered. Each module employs internal voltage regulators to maintain the same unit performance over the entire power supply range of 11 to 15 VDC. The unit may be operated from any DC supply (negative ground) in the range of 11 to 15 VDC with a current capability of 6 A. This allows for flexibility in powering the unit from a variety of power sources which may be available at the installation site. The unit may be powered from any of the following: a local nominal 12 VDC source, an external AC to 12 VDC power source, or from 48 VDC site voltage by using the correct converter. Most typical installations will use the external AC to 12 VDC power source PS338. 2-2 P.G. 12 VDC TM0054 Alarm Relay Contacts N.O. COM N.C.

SECTION 3. INSTALLATION, OPERATING AND MAINTENANCE INSTRUCTIONS 3.1 UNPACKING AND INSPECTION The following checks are recommended after receipt of the equipment from shipping agent:
1. Check for any external damage that could have occurred in transit. If damage is found, report to the shipping agent and to the supplier immediately. Check that all items on the packing slip are present. If any are missing, report to the supplier immediately. 3.2 INSTALLATION NOTE: The unit attenuator has been factory set to the maximum value (30 dB) at time of shipment. This results in a typical unit gain of 40 dB. The installer must know the base station signal level to be fed into the unit. The gain of the unit must be set to a value such that the Rated Output Power of +19 dBm is not exceeded. The unit must not be operated above this Rated Output Power as specified in Tables 1-1 and in 1-2. The Repeater is designed for mounting on a flat vertical surface. Proceed as follows:
1. Locate a suitable mounting location allowing a clearance to route mating cable and connectors to the unit. Drill four pilot holes on 10.5 x 17.9 inch centers for 3/8" bolts. Refer to the installation diagram shown in Figure 3-1. 2. Mount the unit ensuring there is good air circulation. 3. Set the unit attenuator according to the above note such that the Rated Output Power is 4. Connect "BASE" to the cable leading to the base antenna. 5. Connect "DISTRIBUTION" to the cable leading to the distribution antenna. 6. If desired, connect external alarm monitoring equipment to the interface module relay contact terminals as required. 7. Connect external DC power to the DIN receptacle on the bottom of the unit. The unit may be powered by DC voltages in the range of 11-15 VDC (negative ground). The unit is typically powered with the PS338 AC to 12 VDC adapter provided with the unit. This completes the installation. 3-1 never exceeded. TM0054 P.G. 3.3 OPERATING INSTRUCTIONS When powered, the unit green LED on the Interface module will be illuminated and the alarm relay terminals will be in their normal condition. When the unit is first turned on, the red LED may illuminate briefly and the alarm relay may switch to indicate an alarm condition while the PLLs are locking and the modules are disabled. Under normal operation, only the green LED will be on. 3-2 P.G. 19.20 16.00 17.90 TM0054 4 MOUNTING HOLES FOR 3/8" BOLTS 8.90 9.30 18.00 12.00 10.50 FSCM 38243 R280 Ser i es Rep ea ter M od el R280P-DE PART NO. 001-0280-001 FCC ID P6T1902 Serial Number J2 BASE J1 DISTRIBUTION Figure 3-1 Installation Data 3-3
