ABSTRACT:
The position of a printed circuit filter array is mechanically moved from e sidewall to the center of the waveguide to thereby tune the cut-off frequency of the waveguide. An array of printed circuit elements is placed in the E-plane inside a waveguide and serves as a high pass filter. The printed circuit elements make no contact with the guidewalls that are suspended on a dielectric substrate. A sidewall screw tuner is mechanically coupled through the waveguide wall to the dielectric substrate to physically move the dielectric substrate containing the filter elements to selected positions within the waveguide. The substrate may be moved from a position adjacent the waveguide narrow wall wherein no variation of waveguide cut-off frequency occurs to a position at the center of the waveguide wherein the increase in the waveguide cut-off frequency is maximized.
