L-Xc-Band Dielectric Resonator Filters for High Power Applications

The principles and results of the design of microwave band-pass filters on dielectric resonators (DR) for high level (over 100 W) signals are discussed. Filters have insertion losses less than 1.2 dB at 2.6 % passband, 6.25 % passband at 90 dB level and spurious passband suppression over 60 dB
