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 and high precision surface finishes, tubular filters are ideal for handling high-power applications.
Known for their high unloaded Q, API Technologies tubular filters have inherently broad stopbands with very high rejection levels. Tubular Filters are only available in Bandpass and Lowpass filter designs.
We use silver plating during extreme
low loss applications.
Highest ultimate rejection possible, providing superior out of band attenuation.
Designed to handle up to 5,000 watts with
low loss and sharp rejection.
Our tubular filters have inherently broad stopbands with very high rejection levels.
Precision center-less ground stock
allows extremely tight tolerances.
Tubular filters offer many advantages over other topologies for bandpass & lowpass filters.
Provides excellent harmonic suppression.
