Abstract
We have proposed narrow-band transmitting hybrid filter which puts on the output of the 100kW klystron amplifier for X-band radar application. A transmitting hybrid filter consists of superconducting resonators and conventional cavities. Novel hybrid filter structured with two cascade connections of reflection-type cavities, reflection-type superconducting resonators, and open-stub realizes low power concentration in superconducting resonators. 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 100 kW. Also, this filter had fractional bandwidth of 0.055%. Given these features, the transmitting signal with low spurious and the high density carrier frequency assignment for next-generation Radar applications is expected to be realized by applying these filters.
