Abstract
In this letter, a novel design of X-band rectangular waveguide bidirectional coupler is presented. Through the conversion of coaxial-rectangular waveguide, ladder loading of waveguide and waveguide coupling, the effective methods of matching and coupling are well-improved. This bidirectional coupler has good performance: the directivity is more than 25 dB and the coupling coefficient is 35dB with the deviation of 1 dB from 8.8GHz to 9.9GHz. It can detect a signal of 3KW which is used in high-power microwave measurement system.
