    FUNCTIONAL DESCRIPTION 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.
  • Page 14: 3.2.3.2 Upconverter

    AE04B-A0279 Rev -- FUNCTIONAL DESCRIPTION 3.2.3.2 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.
  • Page 15: 3.2.3.3 Synthesizer

    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. This software is a Microsoft® Windows™ application that allows the operator to input the desired RF frequency and gain setting.
  • Page 16: Programming

    AE04B-A0279 Rev -- 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.

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.
  • Page 24: Appendix B Software Installation

    2.1 Overview 2.1.1 The SMARTpc software provides a means to control and monitor the SelectAmp800 series (and other Smart-equipped Andrew products) locally or from a remote site. 2.1.2 The application software runs on a PC under Windows and communicates with firmware inside the SelectAmp800.
  • Page 25: 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).
  • Page 26 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: 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.
  • Page 27: Appendix Dbattery Back-Up Option

    AE04B-A0279 REV-- APPENDIX D:BATTERY BACK-UP APPENDIX D BATTERY BACK-UP OPTION 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 –40 C, so the actual operating life will be dependent on traffic load and ambient temperature at the time the battery back-up is engaged.
