ABSTRACT:
A pair of oppositely poled PIN diodes is connected in series across a reactive element. First and second switching circuits responsive to a common control network are serially connected between high and low voltage points. The junction between the switching circuits is connected to the common junction of the PIN diodes. When the first switching circuit is made non-conductive and the second conductive, the PIN diodes are forward biased. When the first switching circuit is made conductive and the second non-conductive, the PIN diodes are reverse biased. In this way the reactive element is switched into and out of a tuned circuit.
