  • Abstract
    The cryogenic operation of a low-loss RF switch using a AlGaN/GaN metal-oxide semiconductor heterostructure field effect transistor is reported. At 77 K the channel resistance of the MOSHFET is three times lower and the contact resistance is 20% lower compared to room temperature. As a result, the performance of the MOSHFET RF switch at 77 K is even superior to that at room temperature.
