Micro-Pole Series
The MICRO-POLE® Series of tunable bandpass filters was developed to address applications needing a small, surface mount package. This tunable filter is varactor-based in order to minimize size and power consumption. The varactor design also supports requirements up to 2 GHz (custom designs have been completed). Our standard digital interface is included for ease of integration into your design.

Mini-Pole Series
The MINI-POLE® Series of tunable bandpass filters is optimized for small size, RF Power Handling, Low Distortion, and exceptional Selectivity. The product line includes several standard designs in various bands to support a myriad of applications. Approximate performance is summarized in the Mini-Pole Series Selection Guide.

Maxi-Pole Series
The MAXI-POLE® Series of tunable bandpass filters provides improved passband performance (reduced insertion loss for a given bandwidth) in a slightly larger package. The product line includes several standard designs in various frequencies to support almost any application. Approximate performance is summarized in the Maxi-Pole Series Selection Guide.

Power-Pole Series
The POWER-POLE Series of tunable bandpass filters provides improved RF performance with increased power handling capability and the lowest insertion loss for a given bandwidth. The product line includes several standard designs in various frequencies to support almost any application.

Maxi/4R Series
The MAXI/4R Series of tunable bandpass filters provides 4-poles of filtering, for even better rejection than our standard Maxi-Pole filters. The chassis has been ruggedized to better handle the vibration and shock environments often encountered in customer applications (ie. ground-mobile, airborne, etc.). The product line includes several standard designs in various frequencies.

Extended Range Filter™
The Extended Range Filter is a multi-band bandpass filter designed for integration in JTRS transceivers where small size, moderate selectivity and low power consumption are paramount. It provides digitally tunable bandpass filtering from 30 to 512 MHz.

Mega-Pole™ Series
The Mega-Pole filter series covers the range from 30-400 MHz in three different bands, providing excellent selectivity with low insertion loss. Featuring exceptional RF power handling capability with a high third order intercept, this series can be used for transmitter applications to clean up PA noise and harmonics, high power VCOs or other applications requiring linear, high power RF filtering.
