2.92mm(K Band) RF/Microwave coaxial series was designed with highly rugged physical interfaces in mind that would mate with 3.5mm and SMA dimensions. The 2.92mm(K) series use an air dielectric, with increased the performance up to 46.5 GHz to respond to accordingly to millimeter wave applications. The outer contact ID is 2.92mm, and OD is 4.55 mm. In response to the fifth generation of wireless communications, 2.92 mm(K) series of products are also suitable for millimeter wave product application.
