Abstract
A tuneable E-plane waveguide filter is presented. Tuning is achieved using sliders inserted into the cavities of the insert of the waveguide filter. The sliders are inserted through gaps or notches in the insert, or through notches in the waveguide housing. The positions of the sliders is adjusted to fine-tune the frequency response of the waveguide filter, overcoming limits on narrow relative bandpasses imposed by manufacturing tolerances. When a desired frequency response is achieved, the sliders are fixed in position. Assembly and tuning is less expensive and less complex than tuneable H-plane waveguide filters.
