5G RF Spring Probes

Applications & Functions

Our 5G RF spring probes (multi-pin high-frequency coaxial RF probe assemblies) are ultra-precision testing components engineered specifically for high-speed wireless signal validation and RF (Radio Frequency) testing. Built with a robust flange-mount housing, integrated coaxial interfaces, and micro-precision spring-loaded pins, these assemblies provide temporary, low-loss, and highly stable electrical connections during high-speed data and signal testing, ensuring perfect 50 Ohm impedance matching.

They are widely utilized in advanced telecommunications, smart devices, and high-frequency testing laboratories:

• 5G Base Stations & Antennas: Designed for high-frequency testing and calibration of 5G active antenna units (AAU), MIMO systems, and RF front-end modules.

• High-Speed Semiconductor & IC Testing: Perfect for RF wafer probing, package-level testing, and characterization of advanced high-frequency chipsets.

• RF Module & PCB Board FCT: Used in functional circuit testing (FCT) and ICT fixtures for communication motherboards, smart devices, and automotive V2X telematics modules.

• Aerospace & Defense Electronics: Delivers consistent, low-insertion-loss coaxial signal transfers in radar testing, microwave links, and high-frequency avionics assemblies.

Outstanding Product Features

• Exceptional RF Signal Integrity: Optimized coaxial internal design ensures exceptional signal transmission up to 6 GHz / 12 GHz (and higher on custom models) with minimal insertion and return loss.

• Integrated Flange for Secure Mounting: Features a precision-machined square or custom flange body with installation holes, facilitating easy, accurate, and secure alignment into testing fixtures.

• Multi-Pin Coaxial Configuration: Perfectly integrates multiple signal pins and outer ground shielding in a single micro-assembly to block external electromagnetic interference (EMI).

• Thick Gold Plating & Low Resistance: The plunger, barrel, and housing components feature multi-layer nickel and high-thickness gold plating to prevent the high-frequency “skin effect” and guarantee stable contact resistance.

• Durable Spring-Loaded Design: Outfitted with high-fatigue internal springs that ensure stable, repeatable contact force over 100,000 compression testing cycles.
