Matching Network Design

Design narrowband matching networks

Matching network designs a set of circuits that match the impedance of a given source to the impedance of a give load at a specified center frequency.

Apps

Matching Network Designer

Design, visualize, and compare matching networks for one-port load (Since R2021a)

Objects

matchingnetwork Create matching network for 1-port network and generate circuit object
