Product Details
Stainless Steel Material K type (2.92mm) RF Coxial Connector PCB
Mount
The K type connector, also known as the 2.92 type connector, is a
commonly used millimeter wave connector that operates at
frequencies up to 40 GHz. It can be interchanged with SMA series
and 3.5 series products and features an air interface. With its
small size, light weight, high frequency of use, and reliable
connection, it is widely used in various applications.

Features:
- Air Dielectric: Unlike some connectors that use solid dielectric materials, the
2.92mm connector typically employs an air dielectric. This
minimizes dielectric losses and improves signal integrity at high
frequencies.
- Reliable Connection: The design ensures a secure and reliable connection, which is
essential for maintaining consistent performance in high-frequency
applications. The mating mechanism is robust, providing a stable
contact interface even under vibrational stress.
- Compatibility: Although primarily designed for its unique application, the
2.92mm connector can sometimes be adapted to work with other
connector types like SMA and 3.5mm, offering flexibility in system
integration. However, care must be taken as mismatched connectors
can affect performance metrics.
Application:
- Minimal Signal Degradation: The small size and air dielectric significantly reduce signal
loss and distortion, preserving signal integrity at higher
frequencies where these effects become more pronounced.
- Space Efficiency: The compact form factor enables closer component placement on
PCBs, facilitating the design of highly integrated electronic
systems without compromising performance.
- Durability and Reliability: Brass construction combined with a robust connection mechanism
ensures long-term reliability even under harsh environmental
conditions common in high-frequency applications, such as extreme
temperatures or mechanical stresses.
- Optimized for Millimeter Wave Spectrum: Designed specifically for operation in the millimeter wave range,
the 2.92mm connector's characteristics align perfectly with the
requirements of modern communication systems and radar technologies
that operate at these frequencies.
