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 and conditioning. 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 160 Watts.
MCPA Specifications
The MCPA1900and MCPA850 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:
