2.92mm Connector Series（DC~27GHz）
The 2.92mm Series RF coaxial connector is also called K-type connector and SMK connector,Invented by American
willtron company. The working frequency of the main mode of the 2.92mm connector is the highest Up to 46ghz,
covering the entire 8mm band. With the increasing demand of domestic millimeter wave applications The 2.92mm
connector has become the mainstream millimeter wave connector with the largest market demand, It is the first
choice of millimeter wave connector. 2.92mm connector interface compatible with 2.92mm and3.5mm connector.
