摘要:
采用微带混合集成工艺设计了一款W波段宽带pin管开关.通过建立pin管的Ansoft HFSS模型,实现了开关整体的精确仿真.分析了开关结构中主传输线特性对隔离度的影响,在此基础上采用高阻抗主传输线有效地提高了开关的隔离度,进而展宽了开关的隔离度带宽.为了获得开关的宽带导通特性,采用行波技术补偿pin管反向偏置时寄生参量的影响.为了验证该设计方法的正确性,对所设计的开关进行了加工、测试.测试结果表明:开关在87~103.5 GHz频率范围内,隔离度大于30 dB;在80~90 GHz频率范围内,开关导通时的插损小于1.2 dB;在90~95 GHz频率范围内,开关导通时插损小于1.5 dB.仿真结果与测试结果吻合良好.
Abstract:
A broadband W-band switch is presented using microstrip hybrid microwave integrated circuit. The accurate simulation of entire switch is achieved by building the model of pin diode in Ansoft HFSS(High Frequency Structure Simulator). Effects of the main transmission line characteristics of the switch on the isolation performance are analyzed. The isolation of the switch is efficiently improved using high-impedance main transmission lines and then the isolation bandwidth of the switch is also broadened. To obtain a broadband on-state bandwidth of the switch, the traveling wave technology is adopted to compensate the parasitic parameters of the diode in the reverse bias state. In order to validate the proposed design method, the developed switch is fabricated and measured. The measurement results show that the isolation of the switch is greater than 30 dB in the frequency range of 87 to 103.5 GHz. Insertion loss less than 1.2 dB in the frequency range of 80 to 90 GHz and 1.5 dB in the frequency range of 90 to 95 GHz are achieved under on-state, respectively. The simulation results agree well with the measured ones.
