Abstract :
A new Marchand balun for MMIC is proposed which uses air-gap stacked structures and does not need any dielectric process. To design the newly proposed Marchand balun, simple graphical design method was used, which is based on Tsai and Gupta´s generalized coupled lines model. The simple design results were compared with a general full-wave analysis. In this case, HP-Momentum simulator was used.
