Abstract: A multiplexer (102) can be operated in the TE 01δ or HE 11δ modes, each channel of the multiplexer has one bandpass filter, with each filter usually having a plurality of cavities (41,51). One cavity of each filter is a common cavity (51) with all of the other filters of the multiplexer. The common cavity (51) contains one independent dielectric quarter-cut or half-cut image resonator (14,15) for each filter representing a channel of the multiplexer. Each resonator (11-18) is mounted on a suitable support. The common cavity (51) provide a common junction and contains a loop coupling (61) to couple electromagnetic energy between the various channels. The multiplexer has at least one input (31) and at least one output (31).
