Abstract
An inductive strip waveguide band-pass filter includes a conductive movable wall which can be set to various positions to allow a varying 'A' dimension, thereby setting controllably the center frequency of the filter over a predetermined range. If the inductive strip filter includes multiple synchronized resonant cavities, the resonant cavities remain synchronized for all positions of the movable wall. The position of the movable wall can be set manually or by a motorized control mechanism.
