Two kind of balun transformers are composed of a balun transition and an impedance matching circuit. Both of them have good performance and compact size. Chemical etching compatible with the common microwave circuit manufacturing process is employed to make them. Using the odd-mode analysis and commercial microwave software to design the balun transformer. It is more accurate and more efficient than the conventional method to make balun transformer only designed by experience and experiments. These balun transformers can be used in UHF and VHF band. Actually, we have put them into sampling phase detector successfully.
