Low-loss High-power Cryogenic RF Switches using III-Nitride MOSHFETs
Agency / Branch:
DOD / NAVY
We propose to carry out research and development of highly efficient broadband cryogenic switches using voltage controlled 2D electron gas in III-Nitride heterostructure field-effect transistors (HFETs). Due to extremely high electron density in the 2D channel formed at the AlGaN/GaN interface, III-Nitride HFET - based RF switches offer low insertion loss, lower than that of pin diodes and quite comparable to that achievable with MEMS switches. As compared to MEMS and other switch types, III-N HFET switches have much higher switching powers, shorter switching times, excellent temperature stability. Importantly, the HFET performance is expected to actually improve at cryogenic temperatures.
