Summary:The invention relates to a power divider and filter device structure that can particularly be used as an input circuit for an Input Multiplexer (IMUX) device used in telecommunication systems. The device according to the invention comprises one input port and several output ports, and is configured so as to make several cavities in which resonating posts are located, one post per cavity. The cavities communicate some with the others by means of openings. Cavities are arranged in such a way that and input signal incoming the input port propagates through the device by coupling. The cavities and the resonating posts are configured and arranged in such a way that, as it passes through the device, the input signal is, by one and a same operation, filtered and split in as many output signals as the outputs the device comprises, the energy of the input signal being spread out between the outputs.
