Abstract :
This paper presents the design of a microstrip diplexer using step impedance resonator (SIR) with folded hairpin structure. The diplexer consists of two third-order Chebyshev bandpass filters operating at 0.9GHz and 1.8GHz within GSM frequencies band. A diplexer is constructed by connecting two filters to a Y-junction. There is no spurious responses reside within the two passband frequencies. A well agreement between simulation and experimental results has been obtained.
