Abstract
Wide bandwidth filters are of interest in current and emerging wireless and system applications for use in IF circuits or as front end filters. Filters for the new GPS M code and for wireless LAN are required to have bandwidths approaching 4% of center frequency. The paper describes design and fabrication methods for obtaining wide bandwidth filters for GPS and wireless LAN applications using coupled resonator filters. Experimental results are presented.
