ABSTRACT:
The invention relates generally to RF and microwave multiplexers implemented with a plurality of coupled resonators. More specifically, the present invention relates to multiplexers configured to require only a plurality of resonators and series, shunt, cross couplings and input/output couplings between them. It is a main feature of the invention that no microwave dividers, combiners, circulators, or other junctions are necessary for the distribution of microwave energy among the coupled resonators. This is achieved for example by a P-channel multiplexer comprising P rows of coupled resonators, a common input terminal connected to the first resonator of at least one of said rows, and P channel output terminals connected with the last resonator in each row, and at least one coupling between resonators belonging to different rows.
