The PFB Series from Ducommun are Waveguide Bandpass Filters with passbands from 18 to 110 GHz. These mmWave bandpass filters use two types of configurations: the cavity/tunable configuration which offers the best performance and design flexibility and the E-plane configuration which offers low-cost and large volume production solutions. The filters have a passband insertion loss of less than 2 dB and provide more than 50 dB of rejection outside the passband. They are available in modules with rugged mechanical construction and are ideal for use in outdoor units, subsystems, and transceivers.
