Abstract :
This paper presents a planar duplexer consisting of mixed bandpass filters (BPFs) using different tapped resonators. The duplexer is designed based on the general filter design 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.
