1. Introduction
This document presents description of the Andrew Corporation 850 NAC Band RM2
Power Amplifier (60W GMSK / 45W EDGE). The RF100739 (RM2 850) amplifier is a
medium power, RF amplifier intended to provide signal amplification. The RF100739
(RM2 850) amplifier is compatible with GSM and EDGE air interfaces operating in U.S.
domestic cell sites where FCC compliance is mandatory.
The RF100739 (RM2 850) power amplifier includes 3 lines of RF amplification ("TX
paths"). Each TX path is capable of supporting both GMSK and EDGE standards on the
NAC band (869 MHz to 894 MHz). Each TX path is rated for 45W output with EDGE
signal, and 60W with GMSK signal.
2. RF100739 (RM2 850) Specifications
