Summary:The fast growing demand for microwave communication technologies, such as broadband wireless and satellite communication, point-to-point radio links, as well as a variety of radar systems, brings up stringent requirements to modern microwave filter design techniques aimed at minimization of electromagnetic interference, cross talks and jamming. The most critical electrical requirements (such as low insertion loss, greater skirt selectivity and flat group delay), applied to the front-end filters and having a direct effect on the RF system performance, create a traditional, straightforward way of filter design not always acceptable. In a number of cases, the physical dimensions, weight and cost also become an essential factor driving the design approach. Today, when the highly competitive business environment allows little time for the design and development of high performance filters, the knowledge and understanding of "nontraditional" filter configurations, based on nonadjacent resonator coupling, can be a crucial contributing factor to a successful project completion.
