"Current spaceborne communication systems and missile seeker systems require parallel advances in the W-band (94 GHz) multifunction phase array antenna systems. Relatively large aperture areas of the existing antenna systems radiate heat rapidly into spacefrom the RF components. Also, the existing low-phase noise, tunable local oscillators (LO) used for the RF front-ends of the spaceborne communication systems are external, relatively heavy and bulky. A small low-cost, light weight power and thermalmanagement system integrated with the RF system, which occupy less space si needed. The proposed light weight, lwo cost, 94GHz phase array transceiver antenna will have excellent thermal management and exceptional power and resolution. The proposed allMMIC 94GHz aperture coupled transceiver antenna will take care of the thermal management issue by taking advantage of the aperture coupling. It has a novel low phase-noise LO which include a TLC designed 47GHz DRO followed by a TLC's doubler MMIC. Thereare a wide variety of possible post appications in both commercial and defense sectors in addition to the missile seeker,smart weapon, and radiometry applications. The proposed project will have potential use fo the Federal Government in telecommunicationsportable and Satellite applications as well as radar and meteorological sensing systems. The potential for high precision radar, tracking system in commercial telecommunication systems is enorm
