Abstract :
This paper describes a compact duplexer for 400 MHz band land mobile radio communication equipment. The duplexer developed here is constructed with newly-developed double coaxial Stepped Impedance Resonators (SIR). Some advantages of this duplexer are its compact size, light weight, low insertion losses and wide stopband characteristics.
