2.92-KFKG RF Microwave Coaxial Connector
The name of the 2.92mm connector is named after the inner diameter of its outer conductor. The working frequency of the air medium is up to 40GHz, and it can be interchanged with SMA and 3.5mm connectors. Superior electrical performance and reliable connection are especially suitable for test systems and weaponry, making it one of the most widely used millimeter microwave connectors in the world.
