摘　　要：采用低成本方法设计了一款W波段单刀单掷开关.通过在单独加工的石英基片无源电路上安装倒装PIN管,获得了一款W波段准毫米波单片（Q-MMIC）开关.为了获得低损耗、高隔离度性能,开关设计中采用了3-D PIN管模型和电路补偿结构.测试结果表明开关在88 GHz时插入损耗最小,最小值为0.5 dB;在80~101 GHz频率范围内,开关导通时的插入损耗小于2 dB;在84~104 GHz频率范围内,开关隔离度大于30 dB.整个开关电路尺寸为1.5 mm×3.0 mm.A high performance PIN diode single-pole-single-throw（ SPST） switch for W-band application using a low cost approach was developed. By utilizing flip-chip PIN diodes mounted onto a separately fabricated passive circuit having a quartz substrate,a W-band quasi-monolithic millimeter-wave integrated circuit（ Q-MMIC） switch was achieved. A 3-D PIN diode model and a compensation structure were adopted to acquire a low loss and high isolation switch. The measurement results show the minimum insertion loss is about 0. 5 dB at 88 GHz and less than2 dB over the frequency range of 80 to 101 GHz. The isolation is greater than 30 dB from 84 to 105 GHz. The total size of the switch is 1. 5 mm × 3. 0 mm.
