Abstract
A microwave filter is composed of a set of circular cylindrical cavities arranged in cascade array and interconnected by irises having cross-slotted apertures for coupling electromagnetic power in two orthogonal TE113 modes. An input port is formed in a first of the cavities and an output port is formed in a last of the cavities. Each port is constructed as a transition between a section of rectangular waveguide and a section of circular waveguide, the section of circular waveguide being a portion of the first cavity and the last cavity, respectively, in the input and the output ports. The cross-sectional aspect ratio of the rectangular waveguide is 2:1. The ratio of a diameter of the cavity to length, as measured along a cylindrical axis in each cavity, is 0.26 thereby to provide for increased bandwidth while minimizing dispersion and transmission loss.
