CAD procedure for the double-layer broadside-coupled Marchand balun Conference Paper

abstract

• New design equations and a new computer-aided design (CAD) procedure for the double-layer Marchand balun, constructed of broadside-coupled microstrip lines, are presented, based on the derived scattering parameters and a circuit synthesis technique. The developed procedure can determine accurately and quickly both initial electrical and physical parameters of the balun for achieving a desired performance, as well as provide an accurate and simple analysis. Calculated results for a GaAs MMIC balun designed by this procedure are compared to a general full-wave analysis, and good performance and agreement are obtained.
