Description

Millitech series FIB iris bandpass filters have a narrow passband in the range of 1% to 15% of center frequency. These filters offer low insertion loss in the passband with a wide range of passband frequencies. Filters in this series are available from 18 to 220 GHz, and can handle up to 10 Watts. These filters also offer excellent rejection at high and low side rejection frequencies. Characteristics of the filter can be modified to suit specific rejection requirements.

Series FIB filters are constructed using rugged waveguide channel housing and are precision machined. Standard filter response is of a Chebyshev design. Consult Millitech for alternate topologies.
