Multi-Band Transceiver System
Introduction
1.4 S
YSTEM
The transceiver is constructed in a modular configuration. Common to the configuration
for any frequency band of operation is a base module which provides the M&C, Power
Supply, and Reference function. Band-specific BUC and BDC modules can be mounted
to the base module with clip-type fasteners. BUC and BDC modules for other bands and
spares for all modules are stored in a transit case until needed.
