Pole/Zero's standard MICRO-POLE®, MINI-POLE®, MAXI-POLE®, and POWER-POLE® bandpass filters are 2-pole, constant Q designs and are aligned to provide a close approximation to a Butterworth response. Filter tuning ranges are available based on popular communication bands covering 1.5MHz to 1GHz.
MICRO-POLE SERIES The MICRO-POLE® Series of tunable filters was developed to address applications needing a small, surface mount package.
MINI-POLE SERIES The MINI-POLE® Series of tunable filters is optimized for small size, RF Power Handling, Low Distortion, and exceptional Selectivity.
MAXI-POLE SERIES The MAXI-POLE® Series of tunable filters provides improved passband performance (reduced insertion loss for a given bandwidth) in a slightly larger package.
POWER-POLE SERIES The POWER-POLE Series of tunable filters provides improved RF performance with increased power handling capability and the lowest insertion loss for a given bandwidth.
MAXI/4R SERIES The MAXI/4R Series of tunable filters provides 4-poles of filtering, for even better rejection than our standard Maxi-Pole filters.
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 450 MHz.
