Abstract

A novel microstrip balun topology based on common-mode rejection is introduced. The balun is constructed with a short section of coupled line placed above a defected ground structure. Measurements on a PCB sample indicate a successful conversion from single end to differential mode showing 0.7 dB of insertion loss at 3 GHz along with 1-dB bandwidth that extends from 0.7 to 5.6 GHz.
