Broadband single pole multi-throw diode switch with filter providing matched path between input and on port

Claim 1

A SWITCHING NETWORK FOR COMPLETING A PROPAGATION PATH FOR ELECTRICAL WAVES BETWEEN A FIRST PORT AND A SELECTED ONE OF A PLURALITY OF OTHER PORTS, SAID NETWORK INCLUDING A COMMON TERMINAL, A PLURALITY OF SEMICONDUCTOR DIODES EACH CONNECTE BETWEEEN ONE OF SAID OTHER PORTS AND SAID COMMON TERMINAL, SAID DIODES BEING ADAPTED TO BE BIASED TO ALTERNATE CONDUCTIVE STATES, WITH ONE STATE BEING TRANSMISSIVE AND THE OTHER STATE BEING REFLECTIVE TO APPLIED ELECTRICAL WAVES, BIASING MEANS COUPLED TO SAID DIODES FOR RENDERING A SELECTED DIODE REFLECTIVE THERETO, TRICAL WAVES AND THE REMAINING DIODES REFLECTIVE THERETO, SAID SELECTED TRANSMISSIVE DIODE PRESENTING AN EQUIVALENT SERIES INDUCTANCE TO ELECTRICAL WAVES AND SAID REFLECTIVE DIODES PROVIDING SHUNT CAPACITANCE TO A REFERENCE POOTENTIAL FOR SUCH WAVES, AND A TRANSMISSION LINE SECTION CONNECTING SAID COMMON TERMINAL TO SAID FIRST PORT, SAID TRANSMISSION LINE SECTION HAVING AN EFFECTIVE INDUCTANCE APPROXIMATELY EQUAL TO THE EQUIVALENT SERIES INDUCTANCE OF A TRANSMISSIVE DIODE, SAID EQUIVALENT SERIES INDUCTANCE OF THE SELECTED TRANSMISSIVE DIODE AND SAID EFFECTIVE INDUCTANCE COOPERATING WITH THE SHUNT CAPACITANCE OF THE REMAINING REFLECTIVE DIODES TO FORM A FILTER NETWORK WHICH PROVIDES A MATCHED TRANSMISSION PATH BETWEEN SAID FIRST PORT AND THE ONE OF SAID OTHER PORTS TO WHICH THE TRANSMISSIVE DIODE IS COUPLED.
