Design of X-band Waveguide attenuator

Microwave has been largely recognized in todaypsilas world of communications and technology. In fusion reactors various diagnostics like reflectometer, interferometer and radiometer help in getting information regarding various plasma parameters such as density, temperature, plasma fluctuations etc. Various active and passive devices combine to produce such large diagnostic systems and attenuator is one such small component, which is been used, in all the above-mentioned diagnostics since it has a strong capability to reduce microwave power. In the present study design, development and characterization of X-Band waveguide variable attenuator has been done. The designed results match with the experimental results.
