In this article, a novel variable power divider based on varactor diodes is introduced and described in detail.Its main components are 3‐dB couplers, varactor diodes, and lumped elements. The proposed power divider is initially studied using the even‐ and odd‐mode techniques. Then, based on the derived equations and as an experimental verification, the proposed varactor‐based power divider operating at the center frequency of 2.5 GHz is fabricated and its performance is measured. It is shown that the power divider offers a maximum insertion loss of about 1.8 dB with a minimum dynamic range of over 6 dB in the frequency range from 2.3 to 2.7 GHz. The results are discussed. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:1684–1686, 2013; View this article online at wileyonlinelibrary.com. DOI 10.1002/mop.27603
