Coupling Matrix Representation of Nonreciprocal Filters Based on Time Modulated Resonators [PDF]

, 2019
This paper addresses the analysis and design of non-reciprocal filters based on time modulated resonators. We analytically show that time modulating a resonator leads to a set of harmonic resonators composed of the unmodulated lumped elements plus a ...
