Abstract :
A method for increasing the skirt selectivity on one side of a bandpass filter is presented. One such application is the receive filter of a personal communication network (PCN) mobile terminal. An asymmetric synthesis method has been used, realizing finite transmission zeros as cross couplings. A novel microstrip structure has been devised to demonstrate the electrical design. Although the insertion loss measured was greater than that required for a practical system, the procedure is applicable to compact dielectric resonator structures with potentially lower loss capability.<>
