Using the Ring Resonators that we developed in 1991, a CIN Diplexer for VHF TV low channels was developed. In comparison with conventional CIN diplexers consisted of coaxial resonators. It has about a quarter size and weight, and has the same or better electric characteristics and reliabilities. This paper states about the design methods and resulted Characteristics.
