ABSTRACT:
A high-frequency switch circuit includes: a switch section comprised of a field effect transistor having a plurality of bias circuits and a potential generating circuit for generating bias voltages from a control signal and supplying them to the bias circuits. The field effect transistor forms the passage route of a high-frequency signal by turning on and off in accordance with the control signal. The bias circuits are provided to produce a potential difference between the drain terminal and the source terminal of the field effect transistor and to apply bias voltages lower than the voltage of the control signal to the drain terminal, and the source terminal.
