一种新颖双馈电型PIN开关

A novel double-fed PIN diode switch

摘要:

微波光电二极管(PIN)开关速度和功率容量是相互矛盾的2个指标，为同时兼顾改善2个指标，结合半导体器件特性，采取PIN管芯两极同时馈电的设计形式(即双馈电型开关)，经过优化设计，研制出2 GHz~6 GHz单刀双掷PIN开关。与传统型开关电路相比，开关速度和功率容量都得到较好提升，为后续的工程应用奠定了基础。

Abstract:

Microwave Positive Intrinsic Negative(PIN) switch speed and power capacity are two contradictory parameters. In order to improve the two parameters at the same time，combining the characteristics of semiconductor，this study adopted the design of PIN diode feeding simultaneously (namely double-fed switch). By optimized design，Single Pole Double Throw(SPDT) PIN diode switch from 2 GHz~6 GHz was obtained. Its switch speed and power capacity were improved greatly in comparison with traditional switch circuit. This study has laid a good foundation for successive engineering application.
