Features:
1. Mechanical properties
Strong durability: Made of stainless steel, the connector has
excellent corrosion resistance and mechanical strength, and can be
used for a long time in harsh environments.
Convenient installation: Usually adopts double-hole or four-hole
flange mounting, which is easy to be fixed and connected on the
equipment panel. This design not only improves the stability of the
connection, but also simplifies the installation process.
2. Electrical Performance
Low VSWR: VSWR is one of the most important indicators of connector
performance. High-quality 2.92 mmW RF coaxial connectors usually
have a low VSWR (e.g. 1.2 Max), which means less energy loss during
signal transmission and higher transmission efficiency.
High Insulation Resistance: Insulation resistance values are
usually ≥ 5000Ω, which helps to reduce signal leakage and
interference and improve signal transmission quality.
3. Material Characteristics
Stainless steel: The use of high-quality stainless steel material
not only improves the mechanical strength and corrosion resistance
of the connector, but also ensures its reliability and stability in
long-term use.
Gold-plated contact surfaces: Some high-end models of connectors
use gold-plated contact surfaces, which further reduces the contact
resistance and improves the quality of signal transmission.
Application:
1. Radar Systems: Employed in civilian radar systems for detecting
and tracking objects at high frequencies.
2. Broadcasting: Utilized in television and radio broadcasting
equipment to transmit high-frequency signals over long distances.
3. Aerospace: Integrated into avionics systems for communication
and navigation purposes.
4. Scientific Research: Used in laboratory instruments and test
equipment that require precise high-frequency measurements.
