Dielectric Resonator & Loaded Waveguide

Microwave Dielectric Resonator Filters, Dielectric Loaded Waveguide Filters, and Waveguide Filters with connectors. Very high Q for narrow Bandwidth and lowest insertion loss.

Highpass Filters

RF Highpass Filters w/ Connectors

Housing is milled from the solid, with soldered in circuit boards, silver plated wire and solder sealed lids. Power handling, Insertion loss and rejection performance drives size required. Passbands starting from 30 KHz up to 1 GHz.

Microwave LC Highpass Filters/Connectors

Readily customized, these offer the best performance in a small size for maximum pass bandwidths or elliptic responses. Realized with the smallest of components, described as non-distributed or lumped component "LC". Typical 1 W power handling.The reactive components used are air wound coils of silver wire and parallel plate dielectric capacitors,

Surface Mount Highpass Filters

With a full bottom ground plane reflow soldered to the board, and true surface flush pins, these have the best performance in a small surface mount device. 1 MHz to 20 GHz.

Drop-in Highpass Filters

Available with either removable connectors or just pins. This package style is used in subsystem assemblies, when pre-testing and matching can be done with connectors on, then removed and the component "dropped-in" place. 1 MHz to 20 GHz

Substrate Microwave Highpass Filters

Supported substrate. Pass bandwidths from octave to several octaves, inside the metal housing is a thick board microstrip soldered directly to the housing, thus having no possibility of vibration effects. Typical 10 W power handling. Performance equivalent to suspended substrate with the inherent reliability of a 100% supported thick microstrip ...

Stripline & Coaxial Microwave Highpass

High power handling. Pass bandwiths from ocatve to several octaves, a thick etched or milled circuit is realized in air stripline for maximum power handling and minimum insertion loss. Typical 100 W power handling. Superior in performance to suspended substrate because it uses a much thicker conductor. Solder sealed metal housings and lids, CNC ...

Tubular Lowpass Filters

Lowpass & Notch integrated Filters

Lowpass Filter in series with a notch filter. Provides for very sharp close in rejection from the notch filter and extended stopband rejection from the lowpass filter. By combining both filters in one housing and tuning as a unit, better performance is obtained in a smaller package size.

Notch Filters

Miniature Notch Filters

Outstanding bandreject or notch filtering in compact sizes. Rugged construction ensures long term, high reliability performance.

Wideband Notch Filters

These filter have very wide upper passbands, typically 3 - 10 times the center frequency. Useful in suppressing a carrier when measuring harmonics. Shape factor not as steep as cavity.

Notch Filters w/ connectors

Topology depends on Bandwidth and shape factor, with 1/4 wave coaxial the most popular. Useful in rejecting a carrier within a passband with minimal impact
