Coplanar W-Band SPDT and SPTT Resonated PIN Diode Switches

High performance single pole double throw (SPDT) and single pole triple throw (SPTT) switches optimized for center frequencies of 94 GHz and 77 GHz, were realized in coplanar waveguide GaAs MMIC technology using resonated PIN diodes. SPDT switches are shown with 1.3 dB (<1.6 dB) insertion loss and 22 dB (>21 dB) isolation at 94 GHz (entire W-Band). SPTT switches achieve 2 dB (1.8 dB) insertion loss and 38 dB (40 dB) isolation at 94 GHz (77 GHz).
