A millimeter-wave band GaAs pin diode SPST switch MMIC is presented. It is ideal for low loss, high isolation,and high power applications. In the 15-20GHz frequency range, its insertion loss is less than 0, 6dB,its VSWR is better than 1.5, and its isolation is better than 40dB. In the 20-40GHz frequency range, its insertion loss is less than 1. 1dB, its VSWR is better than 1.35,and its isolation is better than 35dB. The output power of the pin SPST MMIC at ldB compression is 2W. These results are obtained using a vertical GaAs pin diode process on MOCVD material.
