Abstract :
A new impedance transforming balun scheme is presented based on the branch line structure with stubs on the vertical branches. The stubbed vertical branch eliminates the unwanted even mode output and provides only the required balun output with opposite phase. Also, the use of stubs reduces the branch lengths by two times the stub length and therefore, helps to reduce the total size of the proposed balun
