  • Transmit/receive module for planar active apertures
    Patent number: 5940031
    Abstract: A T/R module including a multilevel, multichip microwave package having a plurality of gallium arsenide monolithic microwave integrated circuit chips (MMICs) implementing RF switching elements, a variable phase shifter, a plurality of RF amplifiers, and gain trim attenuators and which are located on a planar RF assembly. The module's architecture includes shared or common MMIC circuit elements during both transmit and receive operation modes thus reducing the number of MMICs required while at the same time preloading the supply voltage regulator-modulator which supplies DC power to all the MMIC circuits without degrading T/R module efficiency.
    Type: Grant
    Filed: April 7, 1998
    Date of Patent: August 17, 1999
    Assignee: Northrop Grumman Corporation
    Inventors: Thomas R. Turlington, Patrick G. Farrell, Gerald K. Kane, Gary L. Ferrell, Scott K. Suko, Joseph A. Faulkner, Gregory K. Sinon, Francis W. Hopwood, Andrew J. Piloto
