A broadband high power SPDT switch using shunt discrete PIN diodes is presented. By using shunt SPDT switch configuration, high power performance can be obtained. A novel structure, in which matching sections are added outside of shunt PIN diodes, provides broadband characteristics. The insertion loss of fabricated MIC switch is less than 2.0 dB at 6 to 18 GHz, and is less than 1.5 dB at 7 to 17 GHz. The power handling capability is over 20 W CW at 12 GHz.
