| 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88GHz时插入损耗最小，最小值为0.5dB；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。

| Abstract: | A high performance PIN diode single-pole-single-throw (SPST) switch for W-band application using a low cost approach is 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 is achieved. A 3-D PIN diode model and a compensation structure are 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 than 2 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. |
