2.92mm Male Stainless Steel Straight RF Connectors for CXN3507/MF363A Cable
K-type(2.92mm,SMK) millimeter wave connectors, also called 2.92mm connectors. It's one of the most popular meter wave connectors.The broad frequency range is up to 40GHz. They can be mated with SMA and 3.5mm connectors.
These K-type (2.92mm,SMK) connectors are adopt air interface, which makes them with small in size, light in weight and very reliable in connection, etc.
High-precision 50Ohm coaxial connectors with a 2.92mm (Female) interface are designed for general-purpose RF and microwave applications. These high-performance connectors are widely used in test and measurement environments, spanning cellular to satellite communications, ensuring proper equipment and cable interconnect matching. Constructed from durable stainless steel, these connectors are engineered to endure repeated use. They incorporate an air dielectric and a low-loss plastic center conductor support.
