Narrow-band superconducting hybrid filter for 100kW transmitter of X-band radar application

Summary form only given, as follows. We have proposed a narrow-band transmitting hybrid filter for use on the output of a 100 kW klystron amplifier for X-band radar application. A transmitting hybrid filter consists of superconducting resonators and conventional cavities. Compatibility of the high power handling capability and the sharp skirt feature is possible by this filter. As a result, power handling capability for the hybrid filter was obtained at 100 kW. Also, this filter had a fractional bandwidth of 0.055%.
