GE MDS GPA-9 power amplifier

GE MDS GPA-9 power amplifier

DESCRIPTION

The GPA-9 power amplifier consists of an RF amplifier and PCB mounted to a heat sink, with a DC Power interface, PTT and input/output RF connections on the sidewalls of the chassis. DC power is supplied to the amplifier from a regulated and filtered DC source capable of supplying 10-16 Vdc at a maximum current of 10 Amperes. The DC power source should be current limited or have a protective fuse or circuit breaker.
