Custom High Frequency Lowpass Filters
RLC computerized Low Pass filters are available built to your specifications for both cut-off frequency and rejection regions. This series of filters have cut-off frequencies up to 50.5 GHz with as many as 10 sections. By varying the number of sections you have direct control of the cut-off frequency and the skirt selectivity. Advanced coaxial techniques and optimum selection of component materials ensure stability over temperature and a low VSWR over the entire passband.
