Abstract - This paper presented a novel full band (3.1 - 10.6
GHz) ultra-wideband (UWB) bandpass filter (BPF), including a
brief review of the current progress on the development of the
UWB filters. The filter structure, performance and it application
to the UWB pulse generation and reshaping were described. The
proposed BPF has a simple broadside-coupled microstrip-coplanar
waveguide (CPW) structure, where the CPW was fabricated on
the ground of the microstrip line. The measured results of a 3-
section filter demonstrated the best UWB performance around
the world: bandwidth from 3.0 GHz to 10.63 GHz (@-10 dB);
insertion loss at central frequency about 0.32 dB and very flat
over the whole band; group delay, which is important to an impulse
radio UWB system, about 0.42 ns over the most central band, and
less than 0.95 ns over the whole band. The filter also exhibited a
good performance outside the band, both at low frequency end (to
meet FCC limit) and high frequency end higher than 18 GHz with
insertion loss better than 30 dB. Using the developed filter in pulse
generation and reshaping experiments demonstrated that a steplike
negative pulse with less than 5 ps falltime, generated from a
pulse generator, was reshaped as a Gaussian doublet-like full
