摘要
高速、超宽带微波PIN匹配多掷开关在通信、雷达及电子对抗系统中有着广泛应用的重要器件之一。介绍PIN管的工作机理，分析了应用PIN管设计开关电路时应考虑的因素，进而设计出工作频率为1-18GHz的单刀5掷PIN匹配开关电路，经测试在频率为1-18GHz范围内，插损小于3．5dB，隔离度大于60dB，开关时间小于30ns。
High speed, ultra-wideband and microwave matching PIN multi-throw switch is one of the important apparatus widely applied in communication, radar and electronic counter systems. This article introduces principle of PIN, analyses the factor considered when design switch circuit using PIN. Then,a single-pole five-throw matching PIN switch circuit at 1-18 GHz is designed. Through testing,the main performances of an insertion loss of less than 3.5 dB, the isolation of more than 60dB and the switch time of less than 30ns are obtained.
