Abstract
A PIN diode switching system is provided, particularly for the transmission stage of a mobile radio telephone, in which, when the PIN diode switching system is in a reverse-bias state, a PIN diode is isolated from its power supply via a high-impedance switch and is, thus, biased by its self-rectification to a radio-frequency voltage in order to suppress harmonic formation and radio-frequency attenuation.
