LNODCT (Low Noise Offset Direct Conversion Transmit) 800 MHz Exciter Overview
The Low Noise Exciter and the Power Amplifier (PA) provide the transmitter

of a printed circuit board, a slide in housing, and associated hardware.
The Low Noise Exciter connects to the Base Radio backplane through a 96-pin
DIN connector and two blindmate RF connectors. Two Torx screws on the front of
the Exciter secure it to the chassis.
There are no controls or indicators on the Exciter. Specifications of the transmitter
circuitry, including the Exciter and PAs, are provided in the Base Radio section of
the manual.
