Abstract :
A new type of duplexer is reported that has been realized with a single integrated-structure core and coupling circuit consisting of only an inductor. The unit is a small and high reliability duplexer for mobile telephone equipment. The coupling circuit, and the design and experimental results of the duplexer are described
