Radio Architecture

The radio and control head architecture is depicted in the following block diagrams for each of the radio applications. The
radio deck in all applications is built around a common chassis.
Radio architecture was determined largely by the requirement to integrate in the TK-790 RF modules, and the need to integrate
circuit functions into fewer boards.
Standard radio modules for the radio deck are the Power Supply Board (PSB), RF Power Amplifier (RFPA),
Transmit/Receive Board (TXRX), Radio Control Board (RCB), and Radio Processor Module (RPM).
Standard connectors for all radios are; J1-Antenna, J2-Handset and J3-program connectors. Application or radio type specific
connectors are J4, J5, J6, J7 & J8.
The front panel assembly is made up of the Front Panel Board (FPB), RPM, LCD and Speaker assemblies. The front panel
assembly is installed on the front of the radio chassis for an LC radio. The front panel is also packaged in a remote mounted
enclosure to make a Serial Remote Control Head.
