COUPLING NETWORK DESIGN USING DISCRETE-FREQUENCY DATA

摘要

The problem of broad-band coupling-network design Is one of primary practical importance in electrical engineering. This report is concerned with the derivation of a method for such network design. The design problem may be stated as follows:"To design a two-port coupling network that presents some pre?scribed input impedance, Zin, when terminated in a prescribed load impedance, ZL, both input and load impedances being des?cribed over a certain band of frequencies." A method for the design of practical lossless ladder networks, based on a point-by-point matching in the frequency domain, is described.
