Introduction
This document presents description of the Andrew Corporation 850/1900 Band MCPA
(Multi-Carrier Power Amplifier) amplifiers. The MCPA amplifier is a high power,
mixed-mode RF amplifier intended to provide signal amplification. The MCPA amplifier
is compatible with GSM/EDGE and WCDMA air interfaces operating in U.S. domestic
cell sites where FCC compliance is mandatory.
The Cell band (869 MHz to 894 MHz) MCPA and PCS band (1.93 GHz to 1.99 GHz) RF
power amplifier capable of amplifying multiple signals of different modulation types to a
composite power level of 135 Watts.
MCPA Specifications
The MCPA1900-135 and MCPA850-135 provide linear amplification of multi-carrier,
mixed-mode signals in the cellular and PCS frequency bands, respectively. The 850
Band and 1900 Band MCPA, have the following specifications:
