Abstract

On the basis of a recently developed GaAs technology which allows the realization of millimeter-wave Schottky mixer diodes and MESFETs on the same monolithic chip, different 94-GHz monolithic mixers have been fabricated. The Schottky diodes show cutoff frequencies of up to 2.3 THz. and MESFETs with typical F/sub max/ (MAG=1) of about 90 GHz have been measured. The mixer chips show conversion losses of less than 8 dB combined with noise figures below 6 dB (double sideband). The technology, mixer design, and measurement results are outlined.<>

一个单片94 GHz平衡混频器

基于最近开发的GaAs技术，可以在同一单片芯片上实现毫米波肖特基混频器二极管和mesfet，制作了不同的94 ghz单片混频器。肖特基二极管显示截止频率高达2.3太赫兹。测量了典型F/sub max/ (MAG=1)约为90 GHz的mesfet。混频器芯片显示转换损耗小于8db，噪声值低于6db(双边带)。概述了工艺、混合器设计和测量结果。
