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.
