Waveguide microwave filter

摘要

Microwave filter composed by resonant cavities (CAV) in a rectangular waveguide preferably formed by two bodies (3,4) in which these cavities (CAV) are coupled by means of rectangular windows perpendicular to the direction of propagation in the waveguide. The filter has the corners of the cavities (CAV) rounded where their direction is parallel to that of the electric field inside the waveguide. This permits the filter to be machined much more easily, lowers manufacturing costs and requires less precision.
