Abstract : The patent relates to a high speed switching circuit wherein the polarity of a control pulse determines which of two discrete RF signals is applied to an output terminal. Each RF signal is coupled through input and output transformer circuits to a common output terminal. A pair of diodes connected between the input and output transformers of one circuit are oppositely biased from similarly connected diodes in the other circuit. The control pulse is fed to a center tap of the secondary of each input transformer. Capacitive shunts are connected between each pair of diodes. Thus a simple switch is obtained having low power requirements, high speed and improved isolation.
