Abstract:
A multi-channel transmit/receive (T/R) module for a microwave signal system including a radar system having an active aperture, the module comprising:a substrate;the substrate having a DC interface for electrical connections to a source of logic control signals and a source of DC power;the substrate having an RF interface for RF connections to antenna radiators and to transmit and receive manifolds;the substrate having multiple isolated T/R channel circuits formed integrally therewith;the T/R channel circuits including active circuit components;a system of shielded RF signal routing circuits embodied in the substrate and interconnecting the T/R channel circuits to the RF interface;a first circuit formed integrally with the substrate providing power distribution to the active circuit components of the T/R channel circuits;a second circuit formed integrally with the substrate providing operation of the T/R channel circuits; andat least one of the first and second circuits having common circuitry shared by at least two of the T/R channels in performance of functioning provided by the common circuitry.
