In a coaxial RF coaxial adaptor where it is necessary of coupling two connectors of different series the difficulty is in the RF adaptation due of the different diameters that characterize each series. In ALFA’R these adaptors for coaxial connectors are designed by calculation and simulation softwares and after it is checked and modified with the first prototypes. So ALFA’R gets RF adaptors, both 50 Ω and 75 Ω, with optimum VSWR results and frequency stability. Mechanically they have robust and resistant designs, with different levels of IP sealing according to the version.


We have a very flexible manufacturing program, which allows us to have a multitude of possibilities. In the standard program of manufacture the adaptors are aerial and straight, but also solutions of panel and right angle are available on demand, as well as customized adaptors.
