MICROWAVE POWER DISTRIBUTOR

摘要

PURPOSE:To attain broad band of power distributing characteristics by using a waveguide having a cross lateral cross section as a waveguide forming a Farady rotatory element of a power distributor. CONSTITUTION:The microwave power distributor consists of the Farady rotatory element 12 and a polarized wave device 2. The Farady rotatory element 12 is provided with the waveguide 13 having a cross shape lateral cross section. Further, an unnecessary absorbing resistor plate 8 is provided in parallel with a yz plane in upper and lower slots of the input side of a waveguide 13. Then the waveguide 13 passes through the 1st order mode desired to be transmitted, and the modes of the 3rd order or over are cut off depending on the relation of the cut-off frequency. The 2nd order mode is attenuated by the absorption of the resistance board 8. Thus, the specific band width is increased and then the power distribution characteristic is made broad in the band.
