摘　　要：为了解决W波段接收机保护开关和发射机调制开关芯片问题,基于0.1 mm厚2英寸熔制石英薄膜电路工艺,研制出了应用于W波段PIN二极管单刀单掷开关。为了考察开关性能的一致性,随机抽取了3个SPST开关作了测试,测试结果为,在76-85 GHz频率范围内,开关插损小于1.3 d B,不一致性小于0.5 d B;开关隔离度大于20 d B;开关响应时间、导通时间、关断时间小于20 ns;开关尺寸3.2 mm×3.2 mm。结果表明,该开关可作为接收保护开关和发射调制开关应用于W波段收发组件中。A W-band GaAs PIN diode SPST switch was developed based on the 0. lmm thick and 2 inch thin-film fused quartz technology. Three SPST switches are randomly selected and measured. In 76 - 85 GHz, the measured results show that the insertion loss is less than 1.3 dB with difference less than O. 5 dB, the isolation is better than 20 dB, response time, switch on time, switch off time are both less than 20 ns. The circuit size is 3.2 min×3.mm. The proposed switch can be applied in W-band transceiver modules as a receiver protection switch and transmitter modulation switch.
