Transistor t-r series switch with collector-emitter capacitance tuned with anti-resonant circuit

Claim 1

IN COMBINATION A FIRST TRANSISTOR WITH COLLECTOR, EMITTER AND BASE ELECTRODES, A RECEIVER HAVING AN R-F INPUT STAGE COUPLED TO SAID COLLECTOR ELECTRODE TO RECEIVE CURRENT THEREFROM, AN ANTENNA CONNECTED TO SAID EMITTER ELECTRODE TO PASS CURRENT THERETO, D-C POTENTIAL MEANS CONNECTED TO PASS TRANSISTOR CURRENT THROUGH SAID EMITTERCOLLECTOR PATH, AN ANTI-RESONANT CIRCUIT TUNED TO THE RECEIVER R-F FREQUENCY COUPLED BETWEEN SAID EMITTER AND COLLECTOR, A SECOND TRANSISTOR HAVING COLLECTOR, BASE AND EMITTER ELECTRODES, ONE OF SAID TRANSISTORS BEING NPN AND THE OTHER PNP, A TRANSMITTER R-F OUTPUT STAGE CONNECTED TO SAID COLLECTOR OF THE SECOND TRANSISTOR TO RECEIVE R-F CURRENT THEREFROM, SAID ANTENNA CONNECTED ALSO TO THE EMITTER ELECTRODE OF SAID SECOND TRANSISTOR TO PASS R-F CURRENT THEREFROM, AND SWITCHING MEANS CONNECTED TO THE BASES OF BOTH TRANSISTORS TO SET ONE IN A CONDUCTION STATE UPON RECEIPT OF A NEGATIVE POTENTIAL AND TO SET THE
