Coupler switches
Abstract
Abstract THE PARASTIC ELEMENTS ASSOCIATED WITH SWITCHING DIODES IN THEIR HIGH AND LOW CONDUCTIVITY STATES ARE DUALIZED. IN ASSOCIATION WITH A QUADRATURE HYBRID COUPLER, ONE HIGH CONDUCTIVITY DIODE AND ONE LOW CONDUCTIVITY DIODE FORM A BALANCED BRIDGE NETWORK WHICH INHIBITS SIGNAL TRANSMISSION. UPON SWITCHING ONE OF THE DIODES SO THAT BOTH ARE IN THE SAME CONDUCTIVITY STATE, THE COUPLER-DIODE NETWORK FORMS THE EQUIVALENT OF EITHER A SERIES-CONNECTED, SERIESRESONANT CIRCUIT, OR A PARALLEL-CONNECTED, PARALLEL-RESONANT CIRCUIT, DEPENDING UPON THE CONDUCTIVITY STATE OF THE DIODES, BY CASCADING COUPLERS, A SWITCH HAVING AN ARBITRARILY HIGH ATTENUATION IN THE "OPEN" STATE, AND A SPECIFIED BAND-PASS CHARACTERISTIC IN THE "CLOSED" STATE IS PRODUCED. A SIMILAR ARRANGEMENT USING MAGIC-T HYBRIDS IS ALSO DISCLOSED.
