Abstract

We have proposed narrow-band filter for transmitter of Radar application. A transmitting hybrid filter consists of superconducting resonators and conventional cavity. Novel hybrid filter structured with sandwich in superconducting resonators between two cavities 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 537 W. 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.
