Several monolithic integrated circuits with state-of-the-art performances have been successfully developed for a W-band (75- to 110-GHz) channelized monolithic receiver. The receiver comprises one four-channel multiplexer, four balanced mixers, four IF (intermediate frequency) amplifiers, and four Gunn local oscillators. All will be monolithically integrated into only three chips. The authors report on the design, fabrication, and performance of each monolithic component and describe the complete W-band four-channel receiver integration. State-of-the-art performance includes 5-dB insertion loss and 25-dB rejection for the W-band, four-channel monolithic multiplexer, less than 10-dB conversion loss over a 13-GHz bandwidth for the W-band ion-implanted mixers, and 13 dBm output at 63 GHz and 7.7 dBm at 96 GHz for the monolithic Gunn oscillators. > |
