Abstract :
An asymmetric, broadside-coupled Marchand balun for wideband millimeter wave applications is presented. The balun based on the modified off-center frequency method achieves 34-110 GHz operation bandwidth and exhibits minimum insertion loss of 4.7 dB at 54 GHz. To the author´s best knowledge, this is the widest operational bandwidth among the recently published millimeter wave baluns in silicon technology.
