3.2.7 Battery Back Up Option
The battery back up (BBU) provides emergency operating power in case of AC power loss. Under normal
conditions, the BBU is charged by an intemal charger. If AC power loss occurs, the BBU automatically
comes on-llne and this condition is reported to the status and control module. The BBU will power the
SelectAmp for approximately two hours. The unit has been sized for back up capability over the full -40'
to +60°C_ temperature range.
3.2.3 Mounting Kit Options
A mounting kit (Andrew PIN: EENCL-90004) is available for installing the unit on walls or poles. Installation
instructions are included with the klt.
3.3 Programming
The amplifier and channel number are set by connecting a laptop computer with the supplied cable and
adapter to the LOCAL port. Remote access is available by wireline connection to the RJ-11 port.

FUNCTIONAL DESCRIPTION
3.2.3.2 Upconverter
The upconverter board mixes the filtered 140 MHZ IF with a signal from the synthesizer and outputs the
same frequency that was input to the downconverter. Like the downoonverter, each upoonverter path
consists of a mixer and two gain stages. 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
condltion.
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 status and control
module. The uplink and downiink frequencies are set with a computer that has Andrew designed
frequency control software installed on it. This software is a Microsott Vlfindows application that allows the
operator to input the desired RF frequency and gain setting. The frequency of the synthesizer is
determined as follows:
Uplink = 1710 MHz + (50 KHz x N)
Downlink = 1790 MHz 4» (50 KHz x N)
Where N = Channel Number (0-1199)
The status and control module converts the operators input to the appropriate frequency command for the
synthesizer. The output of the synthesizer is divided into a downconverter path and an upoonverter path.
3.2.4 Power Supply
The power supply assembly consists of an in—line EMI filter, switching power supply. and interface cable.
The power supply accepts a 90 to 264 VAC input and outputs +24 VDC for use by the rest of the amplifier.
Power is distributed to the active modules through the interconnect board.
3.2.5 Status and Control Module
The status and control module includes a microprocessor to monitor module status, control LNAIAttenuator
gain and Channelizer module channel settings. Nine pin D-subminiature connectors distribute power to.
and return status from the modules. A 2400 baud modem is also included for remote monitoring by
telephone wireline connected to an RJ-11 connector. The operator can control the unit locally from a PC
RS-232 port connected to an RJ-45 connector on this board.
3.2.6 Power Amplifier Module
The power amplifier module provides 45 dB of gain for the amplifier. it's maximum output is 10 Watt:
CDMA. The module provides fault status. temperature fault, and output power level indications.

CHAPTER 3
FUNCTIONAL DESCRIPTION
3.1 ~OVERVIEW
The SelectAmp Channeiized Amplifier accepts a broadband input in the 1850-1910 MHz uplink and
1930-19Q0 MHz downiink bands, and selectively passes one CDMA discrete channel in each band while
rejecting the others. This is accomplished by downoonverting the desired signals to a 140 MHZ IF and
using narrowband SAW filters to provide adjacent channel rejection.
3.2 FUNCTIONAL DESCRIPTION
Each path in the SelectArnp consists of four major modules: Diplexer, LNAIAttenuator, Channeiizer, and
Power Amplifier. Power is provided by a +24V power supply and by regulators in the Status and Control
Module. Power distribution and status reporting is also provided by the Status and Control Module.
Diplexing of the uplink and downiink signals is accomplished by diplexer filters tuned to the required PCS
band (AID, BIE, and FIG).
These modules perform the function of selecting one 1.25 MHz channel out of a predetermined PCS band
for amplification.
3.2.1 Diplexer
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 uplink band. the other side for the downlink band. insertion
loss of each filter is 2 dB maximum and 65 dB minimum rejection to the opposite band.
3.2.2 LNAIAttenuator
The LNNattenuator module contains three gain stages and a digitally controlled attenuator. The overal‘
gain of each path eon be adjusted between 65 and 95 dB.
3.2.3 Channelizer
The channelizer module contains three boards shielded by aluminum dividers. These three boards. whicl
are described below, provide the channel selectivity for the SeiectAmp. Channeiizer module gain is 24 di
minimum.
3.2.3.1 Downconverter
The downconverter board consists of a mixer driven by a synthesizer, a SAW filter centered at 140 MH.
with a 1.5 MHZ, 3 dB bandwidth, and two gain stages. The DC current draw of each gain stag'e i
monitored by a window comparator for status. The window comparator will indicate a fault, if the gai
stage has an open or short failure. The output of the down converter is fed to the upoonverter board.

CHAPTER 2
OPERATIONAL OVERVIEW
2.1 4 OVERVIEW
The SelectAmp channelized amplifier accepts a broadband input in the 1850 - 1910 uplink and 1930
-1 990 MHz downlink bands, and selectively passes one CDMA discrete channel in each hand while
rejecting the others. This is accomplished by downconverting the desired signals to a 140 MHz
intermediate frequency and usrng narrcwband SAW filters to provide adjacent channel rejection.
2.2 RF DISTRIBUTION
The amplifier contains two paths; forward for the base station, and reverse for the mobile signal. Each
path includes a diplexer, low noise amplifier, channelizer. and power amplifier. The diplexers and
cl'rannelizers determine the frequencies to be amplified
2.3 POWER DISTRIBUTION
Main power for the amplifier is provided by a 12 amp power supply operating at +25 VDC. The power
supply accepts 90 - 260 VAC inputs. The interconnect board distributes +25 volts, +5 volts, and -5 volts
to the various modules.
2.4 CONTROL DISTRIBUTION
The operator has control over the gain and operating frequency of each path. Computer inputs for gain
and channel settings are routed to each low noise amplifier and channelizer. The gain setting is a four
bit word that sets gain from +2 to +32 dB. The channel setting is a three wire serial input to a synthesizer
in each channelizer. Each module outputs a status message to indicate the overall condition of the active
devices. If an active device fails. the module reports a fault.
