K2.92 Male Stainless Steel RF Coaxial Connector for 1#Semi-rigid/Semi-flexible Millimetre Wave Cable
The high-precision 50Ω coaxial 2.92 mm (female) connectors are designed for general-purpose RF and microwave applications. These high-performance connectors are widely used in various test and measurement environments, from cellular to satellite communications, ensuring proper equipment and cable interconnect matching. Manufactured from durable stainless steel, these connectors are built to endure repeated usage. They are characterized by an air dielectric and a low-loss plastic center conductor support.
Features:
1. Appearance and Structural Features:
The K2.92 connector gets its name from the inner diameter of the external conductor, which measures 2.92mm.
This connector uses an air dielectric to help improve transmission efficiency, especially at high frequencies.
Design-wise, the K2.92 connector has a structure similar to SMA and 3.5mm connectors but is more compact and suited for higher frequency applications.
2. High-Frequency Performance:
The K2.92 connector is designed to support operational frequencies of up to 40GHz, covering the needs of the millimeter wave band.
Its optimized design ensures that the connector maintains a low Voltage Standing Wave Ratio (VSWR) and low insertion loss at frequencies up to 40GHz, significantly enhancing transmission quality and efficiency.
