Abstract :
This paper presents a planar duplexer consisting of mixed band pass filters(BPFs) using different tapped resonators. The duplexer is designed based on the general filter theory and tap-coupling technique. The actual duplexer is fabricated by coplanar waveguide(CPW) structure. The results of this study lead us to the conclusion that the proposal is useful for realizing the high performance planar duplexer fabricated without increasing the number of elements.
