Waveguide Filters

Microwave filters are a fundamental component in the satcom industry’s signal processing. They allow signals to pass within their passband and block signals outside of the passband. Important transmission chracteristic specifications include isolation/rejection, the steepness of the bandedge (roll-off), insertion loss, return loss and group delay characteristic. The filters mechanical dimensions go hand in hand with its isolation and steepness. The higher the filter order, the better is the isolation to the stopband. A higher order filter provides more rejection, requires more space and has higher insertion loss.

High Q-Factors / Low insertion loss
High power handling
Excellent temperature stability
Best return loss
High stop-band rejection
