A novel double-fed PIN diode switch

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.
