AE04B-A0279 Rev -- FUNCTIONAL DESCRIPTION CHAPTER 3 FUNCTIONAL DESCRIPTION 3.1 OVERVIEW The SelectAmp CDMA 800 bi-directional channelized amplifier provides selective frequency amplification of user specified frequencies in the SMR, Cellular, and ESMR bands. This unit will selectively filter for one 1.25 MHz or 5 MHz channel, depending on the part number ordered, in the Uplink and Downlink band as determined by the operator.
AE04B-A0279 Rev -- 3.2.3.2 FUNCTIONAL DESCRIPTION Upconverter The upconverter board mixes the filtered 70 MHz IF with a signal from the synthesizer and outputs the same frequency that was input to the downconverter. The upconverter consists of a SAW filter centered at 70 MHz with a 1.5 MHz or 5 MHz 3 dB bandwidth, depending on the part number ordered, a mixer and gain stages. The DC current draw of each gain stage is monitored by a window comparator.
AE04B-A0279 Rev -- 3.2.3.3 FUNCTIONAL DESCRIPTION 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 downlink frequencies are set with a computer that has Andrew designed frequency control software installed on it.
AE04B-A0279 Rev -- 3.3 FUNCTIONAL DESCRIPTION PROGRAMMING The amplifier and channel number are set by connecting a laptop computer with the supplied cable and adapter to the RJ-45 (see Figure 1-2) port. Remote access is available by wireline connection to the RJ-11 port. To set a specific channel number or gain, refer to Appendix B. The software enclosed with this unit is designed to provide local or remote control capability for one repeater.
AE04-A0279 Rev -- MAINTENANCE CHAPTER 4 MAINTENANCE 4.1 MAINTENANCE PROCEDURES The SelectAmp contains no user-serviceable parts. To verify operation, check the amplifier against the electrical specifications provided in Chapter 1. If the amplifier does not meet these specifications, call 972952-9894 Monday through Friday, between 8:00 a.m. and 5:00 p.m. CST, for instructions regarding return of the defective unit for repair.

AE04B-A0279 Rev -- APPENDIXA: AMPLIFIER INSTALLATION 2. Connect a signal source to the null antenna. Make sure the frequency of the signal source is well away from the BTS frequency, and set the source power level to 0 dBm. Set the spectrum analyzer to the signal source frequency and measure the power level at the Donor antenna cable. The difference between the signal source power and the spectrum analyzer power level reading is the antenna isolation in dB. Record the values.

AE04B-A0279 Rev -- APPENDIX C: APPLICATION NOTES APPENDIX C APPLICATION NOTES The Andrew SelectAmp800 is a two-way on-band repeater with two RF paths. One path is for connection to an antenna directed towards the service providers base station (this would usually be a Yagi or some other directional antenna). The other path is connected to an antenna or suitable leaky feeder cable directed over the area in which the mobile units are to be found. Typical applications for the amplifier are as follows: 1.
AE04B-A0279 Rev -- APPENDIX C: APPLICATION NOTES between the antennas to substantially greater than the gain of the amplifier (otherwise, feedback and oscillation will occur). The isolation can be achieved in many ways including: 1. 2. Physical separation using long feeders to keep the two antennas apart. Directional antennas can be used, if the base station and the mobiles are on opposite sides of the amplifier. 3.
AE04B-A0279 REV-- APPENDIX D:BATTERY BACK-UP APPENDIX D BATTERY BACK-UP OPTION 1. OVERVIEW The SelectAmp series repeaters can be provided with an optional battery back-up, 65ACCE-XXXX-000. This unit is designed to provide the repeater with a minimum of two hours of operation after loss of AC power. This two-hour life rating is for full current draw at –40oC, so the actual operating life will be dependent on traffic load and ambient temperature at the time the battery back-up is engaged.
