ASYMMETRIC RESPONSE BANDPASS FILTER HAVING RESONATORS WITH MINIMUM COUPLINGS

摘要

Asynchronously-tuned coupled resonator cavities (1-8) are implemented having a minimum set of inter-resonator couplings, wherein the filter design incorporates only series and parallel couplings. By way of example, eighth order filter topologies having three transmission zeros, no diagonal cross- couplings, and only eight series and/or parallel couplings can be achieved.< /SDOAB>
