Abstract

This paper proposes a new frequency transformation method for improving the asymmetrical attenuation characteristics of a conventional lumped element band-pass filter (BPF). This new method results in formulas for filter components. The performance of a BPF designed using this method is tested using simulation and measurement. Since the new BPF design method is shown to be very useful for designing BPFs with wide passbands, it is applicable to broadband wireless communication filters, such as those used in ultra-wide band (UWB) wireless communication technology.
