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
1960 CDMA
band (1930 MHz to 1990 MHz) RF power amplifier is capable of
amplifying multiple carriers to a composite power level of 75 Watts.
