DESCRIPTION AND DATA
In addition to the description provided herein, refer to TM
32-5865-012-10 for a general description and illustration of the
tunable coupler. The tunable coupler is a metal enclosure that
contains seven circuit card assemblies (CCAS), two RF relays, an RF
switch assembly, a stepper motor, and four multipin connectors
mounted on the front panel. The tunable coupler controls the RF path
between external transmit and receive equipments and an external VHF
antenna as commanded by digital data inputs.
In addition, the
tunable coupler receives antenna-deployed switch and DF inputs from
external equipment in the system. The inputs are combined with other
status signals generated in the tunable coupler and output to
external equipment in the system. Tunable coupler power and
input/output connections are made at the front panel (see table 1-1).
