Conmutador de microondas con transistor MESFET encapsulado
, 1985 A packaged GaAs MESFET has been used to implement a fast switch at frequencies around 12 GHz. The insertion loss in the ON state is approximately 2 dB between 9 and 13 GHz. In the OFF state the insertion loss can be higher than 20 dB at a frequency near 12 GHz that depends slightly on the control voltage. At low power levels and with the proper control
