2.92mm PCB Mount RF Coaxial Connectors are precision microwave connectors designed for direct installation on printed circuit boards, providing a stable RF interface for signal transmission up to 40 GHz. With a characteristic impedance of 50Ω, these connectors support reliable transitions between PCB transmission lines and coaxial cable interfaces while maintaining controlled impedance, low insertion loss, and stable return loss. 2.92mm PCB Mount RF Coaxial Connectors are widely used in microwave communication equipment, RF modules, high-frequency test systems, radar electronics, satellite communication, and semiconductor measurement applications.
This product category includes both through-hole and surface-mount configurations, allowing engineers to select suitable connector structures according to PCB layout and assembly processes. High-temperature dielectric materials enable reflow soldering up to 260°C, while multiple grounding pins provide improved mechanical stability and grounding performance. Precision machining ensures dimensional consistency and compatibility with standard 2.92mm interfaces, supporting repeatable electrical performance in high-frequency PCB assemblies.
