Abstract
A radio-frequency switching device includes first and second radio-frequency channels connected to an input/output terminal. A controllable switching device selects one of the radio-frequency channels in response to a switching control signal. The switching device includes a respective control module connected to each radio-frequency channel. Each control module includes a PIN diode whose cathode is connected to the input/output terminal, and a control transistor whose base is connected to a control input for receiving the switching control signal. A conducting terminal of the control transistor is connected to the anode of the PIN diode.
