960 CDMA Multiple Carrier Power Amplifier Model: RF100978 Operation Instruction Date: Mar 19, 2008 Version. 1.
Introduction This document presents description of the Andrew Corporation 1960 CDMA Band MCPA (Multi-Carrier Power Amplifier) amplifier. The MCPA amplifier is a high power, RF amplifier intended to provide signal amplification and conditioning. The MCPA amplifier is compatible with CDMA air interfaces operating in U.S. domestic cell sites where FCC compliance is mandatory.
The amplifier has been designed to support an instantaneous bandwidth of 15 MHz. Multiple carriers may be placed within a continuous 15 MHz span in the CDMA band and the product shall meet specified performance marks. The amplifier has a nominal gain of 47.5 dB. The MCPA is designed to meet IS-95 specifications over frequency, temperature (-5°C to +55°C), and power level (up to a maximum of 75W RF output power).

The following table is a summary of detailed alarms within the MCPA. The alarms are mapped to front panel LED behavior, as indicated. Additionally, the alarms are available at the D-Sub connector at on the front faceplate of the MCPA.
The following table shows the pin out for the D-sub connector including the alarm pins.
Installation and Operation Set-Up The MCPA must be installed into a shelf that provides fan-cooling. The MCPA requires +24VDC with a current handling capacity of up to 12.4A. An RS-485 interface is provided and must be utilized to configure the PA for operation and monitoring of alarms and status. RF cables connect from a radio source to the SMA-type input; from the Ntype output to a filter-duplexer module. FCC Statements: FCC ID S8L-100978MCPA This device complies with Part 2, 15 & 24 of the FCC Rules.
