High frequency switching circuit
Abstract:
A high frequency switching circuit is disclosed. The high frequency switching circuit is provided with first and second high frequency signal terminals, a control terminal, a field-effect transistor having a drain, a source and a gate. The field-effect transistor is connected between the first and the second high frequency signal terminals so as to switch a high frequency signal. The high frequency switching circuit is further provided with a variable resistance circuit which is connected between the gate of the field-effect transistor and the control terminal.
