Ka Band Cavity Filters
RLC Electronics' Cavity, Comb Line and Interdigital Band Pass Filters are fixed tuned filters that feature sharp stop band rejection and low insertion Loss. These filters are centered in Ka Band (26.5-40 GHz), with rejection carrying up to 50 GHz.
The type of filter selected is usually determined by the percentage 3 dB bandwidth desired (which ranges from 0.2% of fc to 67% of fc). Parallel coupled, round rod, distributed resonators afford small size and high Q to achieve a near ideal bandpass response. Units are constructed to operate over the most severe military environmental conditions.
