Abstract :
A new microstrip ultra-wideband (UWB) differential bandpass filter using two broadband planar Marchand baluns is proposed. Based on the transversal signal-interference concept, a passband with adjustable fractional bandwidth from 80 to 124% can be achieved for the differential mode, while the common mode can easily be suppressed in the whole frequency band. Good agreement is observed between simulation and measurement.
