ASYMMETRIC RESPONSE BANDPASS FILTER HAVING RESONATORS WITH MINIMUM COUPLINGS

摘要

Asynchronously-tuned coupled resonator cav-ities (1-8) are implemented having a minimum set of inter-res-onator couplings, wherein the filter design incorporates onlyseries and parallel couplings. By way of example, eighth orderfilter topologies having three transmission zeros, no diagonalcross-couplings, and only eight series and/or parallel couplingscan be achieved.
