Abstract : The design of a high-power air-cooled microwave SPDT switch which is capable of operation at peak and average power levels of 500 kW and 666 W respectively is described. The unit is of a differential phase shift circulator design employing 90 degrees nonreciprocal phase shift elements which are forced air cooled. The phase shifter design employs dual ferrite toroids, 'floating' in reduced height RG-51 waveguide. Two approaches are compared for heat sinking the phase shifter; namely, the 'H-beam' and the 'I-beam' configurations. The results obtained indicate that the 'I-beam' configuration is superior to the 'H-beam' configuration. The switch exhibits an insertion loss of 0.6-dB maximum and isolation greater than 20 dB over a 100-MHz bandwidth centered at 9.375 GHz. The input VSWR of the switch over the frequency band is less than 1.28:1. (Author)
