An ultra high frequency wideband filter

V. M. Pan, V. F. Tarasov, S. I. Futimsky


An ultra high frequency wideband filter was developed and fabricated. High-temperature superconductive film, sputtered in a sapphire substrate, was used as a resonator material. Loss in the filter pass band is 0.7 dB, the filter pass band is 165 MHz, its central frequency is 1877 MHz. The filter topology and amplitude-frequency responses are given.
