Filters and Multiplexers for Satellite Communications

During the last eight years significant advances have been made in the design and construction of microwave selective linear phase filters prompted by the need for maximum bandwidth utilisation in satellite communications. Very recently design procedures have been developed for selective linear phase channel multiplexers without the need for circulators or annulling networks, thus minimizing size and weight. In this paper a brief review is given of microwave selective linear phase filters and the more complex multiplexer problem with specific results for the symmetrical diplexer case.
