Exciter Module Overview
The exciter, in conjunction with the Power Amplifier or PA, provides the transmitter functions for the Base Radio.
The exciter, which is a part of ‘transceiver’ RF board, consists of a baseband circuit block, a baseband modulator
circuit block, a pre-amplifier circuit block, and a final amplifier circuit block. The transmitter Voltage Controlled
Oscillator (VCO) and frequency synthesis circuitry blocks are also part of the exciter. Other functional blocks in the
exciter include the various DC voltage regulators which drive the different circuits, the digital decoding circuitry
block which interfaces the exciter circuits to the microprocessor in the control section, metering capability, and
exciter to receiver loopback capability for diagnostic purposes.
The exciter interconnects to the control module using an 84-pin flex cable connector. There are no user controls or
indicators on the exciter.
