Abstract :
A concept and design of a high power attenuator for the X-band have been presented. The attenuation is controlled by two PIN diodes. A circuit is based on a ring coupler and it is configured as a reflective one with two external matched loads. Due to poor switching properties of the diodes in the X-band, a special transforming circuit has been proposed. Any attenuation between 1.5 and 20 dB can be obtained with the input VSWR not exceeding 1.5 over the band from 9 to 9.8 GHz
