Abstract

A compact differential ultra-wideband (UWB) bandpass filter with high selectivity based on transversal filter concepts is proposed in this paper. Two transmission zeros and good harmonic suppression can be achieved for the differential mode, due to the two transmission paths with different lengths for input/output ports. Four quarter-wavelength shorted lines are added to improve the passband transmission characteristic for the differential mode. In addition, the common mode can be suppressed easily in the whole frequency band. A prototype with fractional bandwidth 101% and return loss greater than 16.5 dB for differential mode is designed and fabricated; the measured results show good agreement with the theoretical expectations. © 2011 EUROPEAN MICROWAVE ASSOC.
