Abstract

In this paper, a novel microwave active filter based 011 the traditional lumped and transversal filter archilecture is presented. This new filter adopk an active feedback amplifier topology in order to provide higher selectivity. Also, an alternative filler synthesis is derived from this topology for the conventional lumped and traiisversal filter. In order to demonstrate its usefulness, a L-band active filter is designed at GSM1800 center frequency- I.8GHz with 30MHz 3-dB RW and evaluated in terms of computer simulation. These simulated results demonstrate that the proposcd filter architecture has superior performance when compared with the traditional lumped and transversal filter.
