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