AE02B-A3659 Rev --OVERVIEW Document use is restricted to that described on cover2-1 CHAPTER 2 OPERATIONAL OVERVIEW 2.1OVERVIEW The SelectAmp NBPCS-900-3 Paging Repeater accepts inputs in the 928 – 942 MHz paging band, and selectively passes one discrete channel in each band while rejecting the others. This is accomplished by downconverting the desired signals to a 45 MHz intermediate frequency and using narrowband crystal filters to provide adjacent channel rejection. The reverse path is not channelized, passing all frequencies in the 897 – 903 MHz band. 2.2RF DISTRIBUTION The amplifier contains two paths; forward for the base station to pager signal and reverse for the pager to base station signal. The forward path includes a diplexer, low noise amplifier and splitter, channelizer, combiner, and power amplifier. The channelizers determine the frequencies to be amplified and provide the gain control. The reverse path includes a diplexer, broadband module (amplifier and filters), and a power amplifier. 2.3POWER DISTRIBUTION Main power for the amplifier is provided by a 6.7 amp power supply operating at +15 VDC. The power supply accepts 100 - 240 VAC inputs. This +15 VDC output of the power supply is routed to the Control/Distribution board. The Control/Distribution board regulates and outputs the +15 volts, +12 volts, and +5 volts to the various modules. 2.4CONTROL/DISTRIBUTION The operator has control over the gain and operating frequency of the forward paths, and gain only of the reverse path. The gain setting is controlled via front panel accessible pots. The forward channel frequencies are entered through software installed on a PC/Laptop and sent to the Control/Distribution board. The channel setting is then sent via a three wire serial interface from the Control/Distribution to a synthesizer in each channelizer. Each active module in the amplifier outputs status line(s) to indicate the overall condition of the active devices. If an active device fails, the module reports a fault (red indicator) on the front panel. The reference oscillator for the channelizer synthesizers is located on the Control/Distribution board as well.

AE02B-A3659 Rev --FUNCTIONAL DESCRIPTION Document use is restricted to that described on cover3-1 CHAPTER 3 FUNCTIONAL DESCRIPTION 3.1OVERVIEW The SelectAmp Channelized Paging Repeater accepts inputs in the 928 – 942 paging band, and selectively passes one discrete channel in each band while rejecting the others. In the forward channels this is accomplished by downconverting the desired signals to a 45 MHz intermediate frequency and using narrowband crystal filters to provide adjacent channel rejection. The reverse path is not channelized, passing all frequencies in the 897 – 903 MHz band. 3.2FUNCTIONAL DESCRIPTION Refer to Figure 3-1. The amplifier contains two paths; forward for the base station to pager signal and reverse for the pager to base station signal. The forward path includes a diplexer, low noise amplifier and splitter, channelizer, combiner, and power amplifier. The channelizers determine the frequencies to be amplified and provide the gain control. The reverse path includes a diplexer, broadband module (amplifier and filters), and a power amplifier. Diplexing of the forward and reverse channels is accomplished by diplexer filters tuned to the appropriate frequencies. 3.2.1DIPLEXER The diplexer module consists of dual filters with a common port on one end and two separate ports on the other. One side of the diplexer is tuned for the forward channel, the other side for the reverse channel. Insertion loss of each filter is 2 dB maximum and 65 dB minimum rejection to the opposite band. 3.2.2BROADBAND MODULE The broadband module contains three boards, each mounted in its own compartment. The forward channel signals are routed through the LNA/Splitter and Combiner boards. The reverse channel signal is routed through the 901 MHz board. Each board is described in more detail below. 3.2.2.1 LNA/SPLITTER The LNA/Splitter module contains the first active devices in the forward channel path. It consists of a low noise amplifier, 3-way power splitter, and a gain stage and filter per path. The amplifiers bias voltages are monitored for a fault condition and reported to the control/distribution module. 3.2.2.2 COMBINER The Combiner module consists of a 3-way power combiner, a gain stage and filter, and a level detector circuit.

SelectAmp NBPCS-900-3 Outline Drawing, rear view. 3.2.3.1 DOWNCONVERTER The downconverter board consists of a mixer driven by a synthesizer, a crystal filter centered at 45 MHz with either a 12.5 KHz (930 MHz channelizer), a 50 KHz (940 MHz ReFlex50 channelizer), or a 25 KHz (940 MHz ReFlex25 channelizer) 1 dB bandwidth. It has one fixed gain stage, and a variable gain stage to provide overall gain adjustment. A Receive Signal Strength Indicator (RSSI) circuit measures the received signal strength and outputs a dc voltage to the Control/Distribution board. The DC current draw of each gain stage is monitored by a window comparator. The window comparator indicates a fault, if the gain stage has an open or short condition. The output of the down converter is fed to the upconverter board. AE02B-A3659 Rev --FUNCTIONAL DESCRIPTION Document use is restricted to that described on cover3-4 3.2.3.2 UPCONVERTER The upconverter board mixes the filtered 45 MHz IF with a signal from the synthesizer and outputs the same frequency that was input to the downconverter. The upconverter consists of a mixer, gain stage, and filter. The DC current draw of each gain stage is monitored by a window comparator. The window comparator indicates a fault, if the gain stage has an open or short condition. 3.2.3.3 SYNTHESIZER The synthesizer board consists of a synthesizer circuit that is driven by a reference oscillator and distribution amplifiers. The synthesizer operating frequency is programmed from the Control/Distribution module. The forward channel frequencies are set with a computer that has Andrew designed frequency control software installed on it. This software is a Microsoft Windows 95/98/NT application that allows the operator to input the desired channel frequency. The Control/Distribution module converts the operator's input to the appropriate frequency command for the synthesizer. The output of the synthesizer is divided into a downconverter path and an upconverter path. 3.2.4POWER SUPPLY The power supply assembly consists of a Power Entry Module and switching power supply. The power supply accepts a 100 to 240 VAC, 3A, 50/60 Hz input and outputs +15 VDC for use by the rest of the amplifier. Power is distributed to the active modules through the Control/Distribution board. 3.2.5CONTROL/DISTRIBUTION MODULE The control/distribution module distributes power to the other modules, receives and processes status and fault information, and provides forward channel frequency control. Power distribution consists of current monitoring of both the forward and reverse channel PA’s, linearly regulating the +15 VDC down to +12 and +5 VDC for various modules. Status functions include monitoring RSSI voltages from the channelizers, monitoring forward output power, and driving the appropriate front panel LED’s. Channel frequency selection information is received via RS-232 from the front pan…
