High power microwave power divider
Abstract
Abstract A MICROWAVE POWER DIVIDER IS DISCLOSED WHEREIN MICROWAVE ENERGY AT A FIXED RECTANGULAR WAVEGUIDE INPUT TERMINAL IS SUPPLIED IN VARIABLE RATIOS TO A PAIR OF RECTANGULAR WAVEGUIDE OUTPUT PORTS OF A FIXED OUTPUT ORTHOMODE TRANSDUCER. THE ENERGY INTO THE RECTANGULAR WAVEGUIDE INPUT TERMINAL IS TRANSDUCED TO THE TE11 MODE IN A MODE CHANGE TRANSDUCER CONNECTED TO THE INPUT RECTANGULAR WAVEGUIDE. A FIRST QUARTER-WAVE PLATE TRANSDUCERS THE ENERGY TO A CIRCULAR POLARIZATION MODE. A SECOND QUARTER-WAVE PLATE, ROTATABLE WITH RESPECT TO THE FIRST QUARTER-WAVE PLATE, TRANSDUCES THE CIRCULARLY POLARIZED ENERGY TO A ROTATABLE LINEAR POLARIZATION MODE, THE ANGLE OF POLARIZATION BEING A FUNCTION OF THE ROTARY SETTING OF THE SECOND QUARTER-WAVE PLATE. THE ORTHOMODE TRANSDUCER, FIXED RELATIVE TO THE INPUT TERMINAL, RECEIVES THE LINEAR POLARIZED OUTPUT FROM THE SECOND QUARTER-WAVE PLATE. THE POWER INTO EACH PORT OF THE ORTHOMODE TRANSDUCER IS A FUNCTION OF THE POLARIZATION ANGLE OF THE LINEARLY POLARIZED ENERGY. THE RATIO OF THE POWER SUPPLIED TO EACH OUTPUT PORT IS THEREFORE CONTROLLED BY THE ROTARY SETTING OF THE SECOND QUARTER-WAVE PLATE.
