What is a 2.92mm (K) Connector?
A 2.92mm connector, also known as a K connector, is a precision RF connector designed for operation up to 40GHz. It offers:
Mechanical compatibility with SMA connectors
Superior high-frequency performance compared to standard SMA
Better repeatability and durability
When used in an end launch configuration, it allows a direct transition from coaxial cable to PCB transmission lines such as microstrip or GCPW.
