Synthesis of Parametrically Coupled Networks

We show that a common language can be used to unify the description of parametrically coupled circuits—parametric amplifiers, frequency converters, and parametric nonreciprocal devices—with band-pass filter impedance matching networks. This enables one readily adapt network synthesis methods from microwave engineering in design devices having prescribed transfer characteristics, e.g., gain, bandwidth, return loss, isolation. review basic practical aspects coupled-mode theory synthesis, then how apply both, on an equal footing, multipole, broadband supplement discussion with range examples reference designs.19 MoreReceived 17 September 2021Revised 15 February 2022DOI:https://doi.org/10.1103/PRXQuantum.3.020201Published by American Physical Society under terms Creative Commons Attribution 4.0 International license.
