Paper Abstract

A novel marchand balun is proposed using multilayer microstrip lines technology. The developed balun achieves he broadband operation and the blocking by introducing rectangle-shape microstrip and a U-shape microstrip coupled line in the conventional marchand balun. Meanwhile, the distribution of the electromagnetic field in the multilayer microstrip circuit has been analyzed. The measured results of the proposed balun agree well with the full-wave simulation results across the bandwidth from 20GHz to 55GHz,the insertion loss and the phase difference is better than 5dB and close to 1800,,respectively, and the circuit size is about 2.6mm *1.5mm.
