1.3 General Description
The MCPA (Figure 1) is a microprocessor controlled, linear multi-carrier power
amplifier (MCPA), which operates over the frequency range of 869 to 894 MHz with a
rated output power of 120 watts total (average). At rated output, the amplifier provides
intermodulation products of better than 63 dBc. The design of the MCPA is entirely
solid state, providing trouble free operation and a minimum of maintenance. The MCPA
includes a high-speed I/O port to receive commands from the host controller. The
MCPA is equipped with microprocessor controlled status monitoring and control
circuitry which monitors key MCPA operating conditions and provides remote status
output via the rear panel I/O connector. Local operating status is provided via front
panel LED indicators. The MCPA is powered by an external (customer supplied) 26-28
VDC power supply.
