Wideband Balanced Filters with Wideband Common Mode Suppression Using Coupled Lines

Progress In Electromagnetics Research Letters, Vol. 65, 49-55, 2017
Abstract
A novel balanced filter circuit with wideband common mode suppression using coupled lines is proposed in this paper. A wideband filter with half open stubs is used to realize two transmission zeros for the differential mode passband. The common mode can be suppressed over 15 dB from 0 GHz to 3f0 (f0 is the center frequency of the passband) with insertion loss greater than 15 dB over the upper stopband. A balanced filter with 3-dB fractional bandwidths of 38% is designed and fabricated. Good agreement can be observed between measured results and theoretical expectations.
