Abstract
A microstrip diplexer with very high isolation is proposed. The diplexer comprises two third-order CT filters and a connecting line between them. The improved CT filter has three adjustable transmission zeros through leading in the coupling coefficient between the source and load. By locating the transmission zero of one channel at the passband of the other channel, very high isolation of the diplexer can be achieved. Good agreements are also achieved between measurement and simulation.
