Abstract: A triple mode dielectric loaded bandpass filter (28) has at least one cavity (30) resonating in three independent orthogonal modes. The triple mode cavity (30) can be mounted adjacent another cavity (32) which may be either a single, dual or triple mode cavity. Any reasonable number of cavities can be used as well as various arrangements of cavities. Inter-cavity coupling is achieved through an iris (34) having two separate apertures (36, 38) that together form a T-shape. The cavities are planar mounted. The fitter (28) is designed for use in the satellite communication industry and results in substantial savings in weight and size when compared to previous filters.
