摘要
A high frequency switch circuit according to the present invention includes a control-voltage-generating circuit. The control-voltage-generating circuit includes a depletion type field-effect transistor, an external-control-signal-input terminal, an internal-control-voltage-output terminal, and a power-receiving terminal of the control-voltage-generating circuit. The field-effect transistor has a grounded gate, a source connected to the external-control-signal-input terminal, and a drain connected to the power-receiving terminal. The internal-control-voltage-output terminal is connected to an electrical connection path between the drain of the field-effect transistor and the power-receiving terminal.
