MCPA modules
The RF modules are ultra-linear amplifiers optimized for high power amplification
of PCS signals. Each RF module provides up to 100 Watts of RF output power.
Multi-module systems have combiner losses, which reduce the output power of
each module by approximately 10%. The RF module has been discussed in
section 1.2.1 The end user is responsible for creating a frequency plan and power
allocation, which ensures that in no case the peak output power of a base station
transmitter exceeds 100 watts.
Amplifier Management Module
The Amplifier Management Module (AMM) contains the system control and
alarm management logic and the interface to external operation and control
systems.
Divider/Combiner
The divider/combiner used in multi-module systems allows the RF modules to
function as a single system. The combiner has an active architecture, which
automatically reconfigures to minimize combining losses if an RF module should
fail.
