Plural hybrid load coupling arrangement for plural transmitters with outputs in phase quadrature

Claim 1

A CIRCUIT FOR COUPLING A PLURALITY OF TRANSMITTERS OF DIFFERENT FREQUENCIES TO A COMMON LOAD, SAID CIRCUIT COMPRISING A PLURALITY OF FOUR-PORT HYBRIDS EACH HAVING TWO PAIRS OF PORTS, ONE PAIR OF PORTS OF EACH HYBRID BEING COUPLED IN A CASCADE BETWEEN SAID COMMON LOAD AND A BALANCING LOAD AND EACH HYBRID HAVING ONE OF SAID PORTS CONNECTED TO A CORRESPONDING PORT OF THE NEXT HYBRID IN THE CASCADE SEQUENCE, AND A PLURALITY OF TRANSMITTERS EACH HAVING TWO OUTPUT TERMINALS ON WHICH APPEAR OUTPUT SIGNALS IN PHASE QUADRATURE RELATION WITH RESPECT TO ONE ANOTHER, SAID OUTPUT SIGNALS BEING FED INTO THE TWO REMAINING PORTS OF A CORRESPONDING HYBRID THROUGH CIRCUITS TUNED TO THE CORRESPONDING OUTPUT SIGNAL FREQUENCY, THE MEANS COUPLING SAID OUTPUT TERMINALS TO SAID TWO REMAINING PORTS BEING SO CHOSEN IN RELATION TO ONE ANOTHER THAT THE SIGNALS FED IN AT SAID TWO REMAINING PORTS COMBINE ADDITIVELY AT THE PORT LEADING TO THE COMMON LOAD.
