【摘要】：采用滤波器综合分析方法,基于分立式AlGaAs/GaAs异质结PIN二极管,根据其等效寄生参数,综合出单刀二掷开关集总参数滤波器模型,以此分析其等效分布参数电路,设计出了118GHz星载辐射计用单刀二掷开关准单片,开关电路尺寸6×2.5×0.1mm~3.通过开关模块封装用波导-微带过渡和键合金带插损的分析研究,研制出了低插损的118GHz开关模块,在110~120GHz,测得开关插损小于3.0dB,插损典型值2.6dB;开关隔离度大于22dB;开关响应时间、导通时间、关断时间、恢复时间分别小于18ns、20ns、10ns、18ns,该准单片作为通道切换开关可集成应用于118GHz收发组件中.
[Abstract]:Based on the discrete AlGaAs/GaAs heterojunction PIN diode and its equivalent parasitic parameters, the filter model of SPDT switching lumped parameters is synthesized by using the filter synthesis analysis method. Based on the analysis of its equivalent distribution parameter circuit, a 118GHz spaceborne radiometer is designed. The size of the switch circuit is 6 脳 2.5 脳 0.1mmm3. A low insertion loss 118GHz switch module has been developed by analyzing the waveguide microstrip transition and bond alloy band insertion loss for encapsulation of the switch module. At 110g / 120GHz, the switch insertion loss is less than 3.0dB and the typical insertion loss is 2.6dB. The isolation degree of the switch is more than 22 dB; The switching response time, the turn-on time, the turn-off time and the recovery time are less than 18 ns respectively. The quasi-monolithic can be integrated into 118 GHz transceiver as a channel switching switch.
