Types of RF Filters
A passive RF filter is a passive multiport device that allows signals to pass through at discreet frequencies but rejects any frequency outside of the specified range. Radio transmitters use low-pass filters to block harmonics that may interfere with transmission signals. These designs use specific topologies based on frequency and power handling requirements.
Bandpass filters are offered with very narrow band high skirts to medium band and broad band with low loss. High power applications have a wide range of topologies such as Cavity, Combline, Interdigital, Coaxial, Suspended Substrate Stripline, Waveguide and mixed-Topologies.
Our Lowpass filters are low loss broad band filters, providing high power applications from a wide range of topologies such as Lumped Element, Coaxial, and Suspended Substrate Stripline as well as multiple topologies. Lowpass filters are mainly designed using the Chebyshev type and for those requiring sharp cutoff the modified elliptic type is used.
Our Highpass filters are broad band filters with low loss offered in high power applications with a wide range of topologies such as Lumped Element, Suspended Stripline, and Multiple Topologies.
Our Notch/Bandstop filters are offered with a very narrow band high rejection to medium band through broad band filters with low loss for high power applications from a wide range of topologies such as Cavity, Combline, Interdigital, Coaxial, Suspended Substrate Stripline, Waveguide and Multiple Topologies.
