These new economic models distinguish from the traditional band reject duplexers as the coaxial tripling elements are changed by the whole-soldered nodes. The filter has a construction that ensures a high thermo-stability due to Invar alloy. A high quality-factor of each cavity is provided by means of application of the pure electro-technical copper and by the silvering of the contacting parts. An adjusting is being implemented on the modern network spectrum analyzers manufactured by Aglient Technologies and Rohde&Schwartz.
