A PIN diode switch suitable for switching radio-frequency voltages has a series circuit of two oppositely polarized PIN diodes, with a control current supplied to the junction between the two PIN diodes through the collector-emitter path of a transistor and through an inductor. The necessity of using a high-voltage power pack to generate a high reverse bias in order to avoid limiting the amplitude of the radio frequency voltage to be switched is not necessary, as in conventional PIN diode switches.
