Abstract
The design of an asymmetric microstrip coupled-line filter with distributed amplifiers is presented in this paper. The proposed filter along with the distributed amplifier decreases attenuation with the increase in the selectivity. These amplifiers further reduce the fringing fields which occur in the preceded filter sections. The proposed distributed amplifier is designed at 5.5 GHz using Agilent Advanced Design System-2009 simulator. An irregular spacing between the coupled lines is introduced in order to improve insertion loss and reduce reflection loss. This filter further possesses high skirt rate along with the high selectivity. The insertion loss of −0.006 dB and reflective loss of −28.772 dB are achieved with a bandwidth of 400 MHz. These specifications make the proposed filter suitable for Wireless Local Area Network (WLAN) applications.
