Transmitter/antenna coupler diplex control system: Eliminates multiple-wire control cables: Limits switching to single-conductor RF coaxial cable
Abstract
In an existing hf transmitter/antenna coupler complex in which an RF automatic or manual switching matrix is to be employed, the information carried by the multiple-wire control cables must be switched in parallel with the information carried by the coaxial RF cable. This report describes the development and testing of a multiple-tone encoded diplexing system which eliminates the multiple-wire control cables, reducing the switching requirement to handling the single-conductor RF coaxial cables.
