A wide-band gysel power divider/combiner based on a modified marchand balun

Abstract

A wideband two‐way Gysel power divider/combiner is presented based on a modified Marchand balun. With a −15 dB input and output return loss criteria, proposed method has a bandwidth of about 53%, while dimensions are still similar to the conventional Gysel power divider/combiner. The structure of the designed planar microstrip in‐phase power divider is fairly simple, practical, and easily fabricated without requiring complex multiple metal or dielectric layers. In addition to CAD simulation and optimizations, with the aid of even‐ and odd‐mode analysis, a mathematical designing framework is also established. To verify the design approach, the proposed divider/combiner is fabricated and measured at the S‐band of frequency. There is a good agreement between simulation and experimental results. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:949–955, 2017

A power divider with high‐power handling capability and enhanced selectivity performance

“…In Ref. , a combined structure with Gysel PD and Balun is proposed for wideband application. However, all the above designs cannot reject the out‐of‐band signal, which means the selectivity is low.…”

A Novel Three-Way Gysel Power Divider/Combiner on Plane Structure

“…Several methods were used to get better bandwidth of Gysel PDC [6]. In [7,8], PDCs are designed for arbitrary impedance terminals or unequal power division.…”
