Abstract:
1. Frequency-separator waveguide module, comprising a diplexer with an input/output access point at a first end of a waveguide with a square cross section, called a square waveguide, two access points made of waveguides with a rectangular cross section, called rectangular waveguides, placed side by side at a second end of the square waveguide, and wherein the diplexer includes a septum positioned in this square waveguide at the end of a central separation region common to the two rectangular waveguides in order to allow the production of two circular polarizations of opposite handedness each associated with one of the rectangular waveguides, each access point by said rectangular waveguides is extended by a filter provided in order to transmit a different frequency band and the septum is a blade in a form of steps which are dimensioned so as to compensate for the reflections of the frequencies respectively rejected by each filter towards the said septum.
