TUBULAR/COAXIAL FILTERS

Tubular/Coaxial filters offer many advantages over other topologies for bandpass and lowpass filters. Because of the mechanical configuration, they offer very broad stopbands and very high rejection.

Using capacitively coupled dielectric spacers, tubular filters are ideal for handling power levels up to 5,000 watts.

Known for their high unloaded Q, Spectrum Microwave tubular filters have inherently broad stopbands with very high rejection levels.

We use silver plating during extreme low loss applications.
