Compact single‐level and multilevel folded‐line RF power dividers

Abstract

AbstractA new design methodology for compact single‐level and multilevel folded‐line radio frequency (RF) power dividers is presented. Simple design equations are developed for compact 3‐dB Wilkinson power dividers with single and cascaded folded‐line C‐sections. The new topologies show a reduction in footprint area to less than 40% of the conventional topology for single‐level compact designs and to less than 17% of the conventional topology for a multilevel compact design. The new compact designs are validated by full‐wave electromagnetic simulation as well as measurements. Excellent agreement is reported. © 2003 Wiley Periodicals, Inc.
