ABSTRACT:
A microwave band branching arrangement for successively coupling frequency sub-bands of a broad frequency band of energy has a coupler for coupling the highest sub-band of frequencies at one end of the arrangement and a series of successive couplers which are each arranged to sequentially couple frequency sub-bands of energy in an ascending order of frequency from the coupler which couples the highest frequency sub-band. By arranging that the highest frequency sub-band is coupled first, it is subjected to a lower attenuation. In further embodiments of the invention, where the arrangement is used, for example, in a repeater station, sub-bands of energy are coupled out, regenerated and amplified, and reinserted by a further coupler into the arrangement for further transmission.
