5G High-Frequency Probes

Applications & Functions

Our 5G high-frequency probes (precision-engineered RF spring-loaded testing pins) are ultra-precision electrical contact components designed for high-speed signal validation, semiconductor IC characterization, and high-frequency communication testing. These probes are engineered to establish temporary, exceptionally stable, and low-noise electrical connections between test equipment and high-frequency test targets, ensuring outstanding signal integrity and precise 50 Ohm impedance matching.

They are widely used in critical electronic and high-frequency communication testing fields:

• 5G Telecommunications & Hardware: Ideal for high-frequency testing of 5G antennas, massive MIMO system modules, and microwave transmission equipment.

• Semiconductor & IC Packaging: Perfect for wafer-level probing, functional test fixtures, and IC socket testing of advanced RF front-end chips and high-speed processors.

• Automotive Radar & ADAS Modules: Designed to test autonomous driving radar modules, microwave transceivers, and GPS/GNSS high-frequency circuits.

• Smart Device RF Testing: Used in automated FCT (Functional Circuit Test) and ICT (In-Circuit Test) fixtures for smartphones, tablets, smart wearables, and IoT communication boards.

Outstanding Product Features

• Optimized High-Frequency Performance: Expertly engineered to support high-speed signal transmissions from 6 GHz to 12 GHz (and beyond on custom designs) with minimal insertion loss and reflection.

• Multi-Step Precision Body: Features a specialized CNC-turned stepped-neck plunger design that optimizes mechanical guide precision and prevents internal friction.

• Premium Gold Plating & Low Loss: Plated with a thick, high-purity gold layer over a nickel underplate, minimizing the high-frequency “skin effect” and maintaining an ultra-low, stable contact resistance (under 30 mΩ).

• Robust Lifecycle & Spring Force: Outfitted with high-durability internal springs to ensure a highly consistent and predictable contact force over 100,000 smooth compression cycles.

• Color-Coded Specification Ring: Features a clear, integrated color identification band on the barrel body for quick and error-free specification identification on high-density test boards.
