Claims

[Scope of utility model registration request]

An F:ET amplifier using an FET includes an FET that amplifies high frequency, an element that switches the drain current of this FET in synchronization with a high frequency signal input to the FET, and a signal generator that generates a pulse to drive this switching element. An FE characterized in that a drain current is caused to flow in synchronization with a high frequency signal input to an FET amplifier.
T amplifier.
