Abstract

A new dual‐band operation scheme is proposed for the branch‐line coupler using two center‐tapped branches. The proposed coupler has two branches with a stub line attached at the center. Only two stubs are required for the dual‐band operation, which reduces the circuit complexity and minimizes the structural change from the conventional branch‐line coupler. © 2008 Wiley Periodicals, Inc.

## Abstract This letter presents a novel dual‐band balun using the branch‐line configuration. We establish design equations for dual‐band balun based on the even‐odd mode method. The proposed circuit operates at 2.45 GHz and 5.25 GHz. The single‐ended power is divided differentially at the balanced
