Hybrid ring structure for reversing the phase of an rf signal in accordance with the level of a two-voltage level signal producing means

Claim 1

AN ELECTRONIC PHASE REVERSAL MODULTOR FOR CONTROLLING THE PHASE SHIFT OF AN R-F SIGNAL PRODUCED BY AN R-F SIGNAL SOURCE TRAVELING TO A LOAD, SAID R-F SIGNAL HAVING A PREDETERMINED WAVELENGTH, SAID ELECTRONIC PHASE REVERSAL MODULATOR COMPRISING: HYBRID RING MEANS HAVING AN EFFECTIVE CIRCULAR DIMENSION EQUAL TO ONE AND ONE-HALF THE WAVELENGTH OF SAID R-F SIGNAL, SAID HYBRID RING MEANS INCLUDING FIRST, SECOND, THIRD AND FOURTH JUNCTIONS, SAID FIRST AND SECOND JUNCTIONS BEING SPACED APART BY ONEHALF WAVELENGTH MEASURED ALONG ONE CIRCULAR DIMENSION OF SAID HYBRID RING MEANS AND ONE WAVELENGTH APART MEASURED ALONG THE OTHER CIRCULAR DIMENSION OF SAID HYBRID RING MEANS, SAID THIRD JUNCTION BEING POSITIONED INTERMEDIATE SAID FIRST AND SECOND JUNCTIONS ALONG SAID ONE CIRCULAR DIMENSION, AND SPACED ONE-QUARTER OF A WAVELENGTH FROM SAID FIRST JUNCTION, SAID FOURTH JUNCTION BEING POSITIONED ALONG SAID OTHER CIRCULAR DIMENSION AND ONE-QUARTER WAVELENGTH FROM SAID FIRST JUNCTION BETWEEN SAID FIRST AND SECOND JUNCTIONS; SIGNAL PRODUCING MEANS FOR PRODUCING FIRST AND SECOND OUTPUT SIGNALS, EACH OF SAID FIRST AND SECOND SIGNALS BEING EITHER AT A FIRST OR A SECOND VOLTAGE LEVEL; FIRST MEANS FOR APPLYING SAID FIRST SIGNAL TO SAID THIRD JUNCTION, SAID FIRST MEANS BEING RESPONSIVE TO THE FIRST VOLTAGE LEVEL OF SAID FIRST SIGNAL FOR PLACING SAID THIRD JUNCTION AT AN EFFECTIVE R-F OPEN CIRCUIT IMPEDANCE WHEREBY THE PATH OF THE R-F SIGNAL FROM SAID R-F SIGNAL SOURCE TO SAID LOAD IS THROUGH SAID FOURTH JUNCTION AND HENCE UNDERGOES A PHASE SHIFT CORRESPONDING TO ONE WAVELENGTH, SAID ONE WAVELENGTH CORRESPONDING TO NO EFFECTIVE PHASE SHIFT; AND SECOND MEANS FOR APPLYING SAID SECOND SIGNAL TO SAID FOURTH JUNCTION, SAID SECOND MEANS BEING RESPONSIVE TO SAID FIRST VOLTAGE LEVEL OF SAID SECOND SIGNAL FOR PLACING SAID FOURTH JUNCTION AT AN EFFECTIVE R-F OPEN CIRCUIT IMPEDANCE WHEREBY THE PATH OF THE R-F SIGNAL FROM SAID R-F SIGNAL SOURCE TO SAID LOAD IS THROUGH SAID THIRD JUNCTION AND HENCE UNDERGOES A ONE-HALF WAVELENGTH PHASE SHIFT, SAID ONE-HALF WAVELENGTH PHASE SHIFT CORRESPONDING TO A PHASE REVERSAL OF SAID R-F SIGNAL.
