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. This is accomplished by downconverting the desired signals to a 70 MHz intermediate frequency and using narrowband SAW filters to provide adjacent channel rejection 2.2 RF DISTRIBUTION The amplifier contains two paths; forward, or downlink, from the base station to the mobile, and reverse, or uplink, from the mobile to the base station. Each path includes a diplexer, low noise amplifier, channelizer, and power amplifier. The diplexers and channelizers determine the frequencies to be amplified. 2.3 POWER DISTRIBUTION Main power for the amplifier is provided by a 14 amp power supply operating at +15 VDC. The power supply accepts 90 - 260 VAC inputs. The interconnect board distributes +15 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 downlink gain from 65 dB to 95 dB, and uplink gain from 55 to 85 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.

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. This is accomplished by downconverting the desired signals to a 70 MHz IF and using narrowband SAW filters to provide adjacent channel rejection. 3.2 FUNCTIONAL DESCRIPTION Refer to Figure 3-1. Each path in the SelectAmp consists of four major modules: diplexers, LNA/attenuator, channelizer, and power amplifier. These four modules are powered by, interconnected by, and monitored by the power supply, interconnect board, and the status and control module respectively. Diplexing of the uplink and downlink signals is accomplished by diplexer filters tuned to the required band (SMR, Cellular, or ESMR). This view shows a third LNA/Attenuator for the diversity option. These modules perform the function of selecting one 1.25 or 5 MHz channel out of the SMR, Cellular, or ESMR 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 LNA/Attenuator The LNA/attenuator module contains gain stages and digitally controlled attenuators. The gain of this module is adjustable to permit the overall gain of the downlink path to be adjusted between 65 and 95 dB, and the uplink path to be adjusted between 55 and 85 dB. 3.2.3 Channelizer The channelizer module contains three boards shielded by aluminum dividers. These three boards, which are described below, provide the channel selectivity for the SelectAmp. Overall gain of the Channelizer module is 5 dB. 3.2.3.1 Downconverter The downconverter board consists of a mixer driven by a synthesizer, and gain stages. The DC current draw of each gain stage is monitored by a window comparator for status. The window comparator will indicate a fault, if the gain stage has an open or short failure. The output of the down converter is fed to the upconverter board. Document use is restricted to that described on cover 3-1 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. The window comparator indicates a fault, if the gain stage has an open or short condition.

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. The status and control module converts the operator's input to the appropriate frequency command for the synthesizer. The output of the synthesizer is split to the downconverter mixer and upconverter mixer. 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 +15 VDC for use by the rest of the amplifier. Power is distributed to the active modules through the interconnect board. 3.2.5 Power Amplifier Modules The downlink power amplifier module provides 45 dB of final gain and is J-STD-008 compliant up to 10 Watts output. The uplink power amplifer module has 27 dB of gain and is J-STD-008 compliant up to 1 Watt output. A thermal sensor mounted on the heatsink monitors the total heat dissipation of the power amplifers. 3.2.6 Interconnect Board The interconnect board distributes power to the other modules, and provides status information and control capabilities at the local and remote connections. Control functions include synthesizer channel selection and individual channel attenuation settings. Status information includes module summary status for the LNA/attenuators, channelizers, power amplifiers and battery backup. 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 internal charger. If AC power loss occurs, the BBU automatically comes on-line and this condition is reported to the status and control module. The BBU has been sized for back up capability over the full –40º to +60ºC tempe rature range and will power the repeater for approximately two hours when ambient temperature is –40ºC. Actual back up time will increase with warmer temperatures. 3.2.8 Mounting Kit Options A mounting kit (EENCL-90004) is available for ease of installation on walls or poles. Refer to Appendix A for installation instructions. Document use is restricted to that described on cover 3-3 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.

The wiring follows North American standards • Black Wire – Line • White Wire – Neutral • Green or Green/Yellow Wire – Ground or Earth 7. Alignment and Test This procedure will allow the installation crew to properly align and test the repeater system. This procedure assumes the antennas and cables are properly aligned and operating correctly. 1. Connect a spectrum analyzer to the donor antenna cable. Adjust the analyzer for a convenient display of the BTS signal, and record the received signal level. Received Signal Level __________dBm Document use is restricted to that described on cover A-5 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. Signal Source Level ________ dBm Spectrum Analyzer Level ________ dBm Isolation ________ dB The isolation value determines the maximum amount of gain allowed for either downlink or uplink path. For the best stability of the system under all conditions, the repeater gain in the uplink or downlink should be at least 10 dB less than the isolation measured. 3. Initial Downlink Gain Setting THE OUTPUT POWER OF THE EITHER PATH MUST NOT EXCEED THE SPECIFIED RATING. IF THE SPECIFIED RATING IS EXCEEDED, THE UNIT MAY NOT BE FCC COMPLIANT FOR SPURIOUS EMISSIONS. Connect the spectrum analyzer to the NULL port of the repeater. Remember, the power rating of the repeater is quite high and there is risk of exceeding the spectrum analyzer maximum input. Place attenuators as required on the spectrum analyzer input. Connect the Donor antenna to the DONOR port of the repeater. The downlink output power of the repeater is equal to the input level measured in Step 1 above, plus the repeater gain. Initially, set the repeater gain so that it meets the isolation criteria specified in Step 2 without exceeding the output power specified in Chapter 1, Table 1-1. 4. Initial Uplink Gain Setting The uplink gain is completely dependent on the system design, and can only be determined through drive testing. It is recommended that the gain be set to minimum, and increased as required to meet system performance requirements. 5. Once the initial settings are made, drive testing is recommended to verify proper coverage.

Tools required One personal computer (PC) with Windows 95, 98, or Windows NT. 2. SMARTpc Lite Software Installation and Configuration 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. 2.1.3 Local connections require a programming cable which is provided with the SelectAmp800. 2.1.4 Remote connections require a PC accessible modem. 2.2 Installation/Configuration Instructions 2.2.1 Install the Software on the PC. 2.2.1.1 Insert the installation disk into floppy drive. 2.2.1.2 Run the setup.exe executable located on the installation disk. 2.2.1.3 The default installation directory is c:\smartpc, but the setup program prompts you in order to allow a different installation directory. 2.2.1.4 After setup is completed, there should be a new program group called SMARTpc Lite. Document use is restricted to that described on cover B-1 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. Extending coverage to within tunnels. This is achieved by the use of a leaky feeder cable running the length of the tunnel attached to the mobile port of the amplifier. A directional antenna would be connected to the base port of the amplifier directed towards the base station. In this way uninterrupted coverage can be extended to within the tunnel. In some cases a Yagi or omni-directional antenna can be used. 2. Extending coverage to within buildings. Many modern buildings incorporate large amounts of reinforced concrete and other metal in their construction and, therefore, act as effective screens to penetration by RF signals. By using localized antenna or leaky feeders within these buildings connected to the mobile port, and a Yagi on the top of the building connected to the base port, coverage can be extended to within these buildings. 3. Local topology, e.g., hills, embankments, etc., can cause propagation blank spots. By using a suitable antenna to cover the area and a Yagi mounted high enough to "escape" the blank spot, coverage can be extended to these areas. 4. Temporary requirements for radio coverage can arise from such events as conferences,, exhibitions, sporting events, etc. These short term events would not justify the expense of a permanent base station. Therefore, an amplifier can be employed to "borrow" channels from a less busy site some distance away that would otherwise be out of range of mobiles units at the event. 5. If a site becomes heavily congested with radio traffic and a neighboring site is under-utilized, an amplifier can be utilized to "borrow" channels from the quiet site for use in the coverage area of the busy site. 6. In areas of low user density, a base station can be under-used. However, it is often impossible to increase coverage from a central point which experiences limits on power levels, mast heights etc. In these instances an amplifier placed some distance away from the base station can be used to extend the coverage in a desired direction. When siting the two antennas for an amplifier, the most important requirement is to maintain the RF isolation Document use is restricted to that described on cover C-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. Vertical separation can be used by mounting the base station antenna high up a mast and the mobile antenna as low as possible angled downwards to separate the two field patterns. It is also necessary when siting the antennas to ensure that the maximum input signals to the amplifier do not exceed the limits for the particular unit being used. If excessive signals do occur, overloading of the amplifier can result in poor intermodulation and signal to noise performance.

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. The unit contains two batteries, a battery charger, and ancillary components for internal temperature control. There are two external connections, one for AC power and one for DC interconnect between the battery back-up and the repeater. The connections are opposite sex to reduce the possibility of swapping power inputs. A 12 foot AC power cord and a 6 foot DC interconnect cable is shipped with the unit. 2. INSTALLATION CAUTION THIS UNIT IS EXTREMELY HEAVY. USE CARE WHEN LIFTING. CAUTION Installation requires only sufficient structural strength of the installation site to support the weight of the unit. The unit should be mounted within 10 feet of an AC power source, and within 5 feet of the repeater. 3.
