Studies from University of California Further Understanding of Microwave and Wireless Technologies (Study and analysis of contiguous channel triplexer based on combining method of two filtering circuits using CRLH and RH isolation circuits)

By a News Reporter-Staff News Editor at Journal of Technology -- Research findings on Microwave and Wireless Technologies are discussed in a new report. According to news originating from Los Angeles, California, by VerticalNews correspondents, research stated, "Several types of multiplexers based on isolation circuits have been introduced and investigated. Combining method of two filtering circuits (CMTC) is one way to make multiplexers based on isolation circuits."

Our news journalists obtained a quote from the research from the University of California, "This method fits well for designing contiguous channel triplexers. A triplexer based on CMTC consists of a conventional transmission line (TL) connected to a diplexer and a composite right/left-handed (CRLH) TL connected to a filter. The triplexer based on CMTC has two significant advantages. One is that it is not necessary to modify the design of a stand-alone filter and diplexer and there is freedom in the choice of filtering circuits. In addition, a designer does not need to perform three-dimensional full-wave optimization, because of a simple and straightforward design concept. In this paper, a triplexer prototype having 1, 1.125, and 1.25GHz center frequencies, is designed and fabricated."

According to the news editors, the research concluded: "The measured results show good agreement with the simulation results."
