基于微带线的W波段宽带pin管开关
Design of broad-band W-band pin diode switch based on microstrip technology
摘要
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 character-istics of the switch on the isolation performance are analyzed.The isolation of the switch is efficient-ly 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 meas-ured.The measurement results show that the isolation of the switch is greater than 30 dB in the fre-quency 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.关键词
