More about RF Test Fixtures

Designed for low-loss signal integrity and repeatable accuracy, these impedance-matched enclosures—ranging from modular R&D blocks to automated pneumatic units

Our RF Test Fixtures are custom-engineered, EMI-shielded solutions designed to provide precise, non-destructive interfacing between your Device Under Test (DUT) and measurement equipment (such as VNAs). They allow RF signals to be transferred, monitored, and measured in real-time without breaking the circuit or affecting performance.

Core Functions & Applications

These fixtures are essential for the design, troubleshooting, and validation of RF circuits. Common applications include:

Signal Analysis – Measuring RF power, frequency, impedance, noise, and signal quality.
Signal Processing – Facilitating RF modulation, demodulation, and signal generation.
Circuit Validation – Ideal for filtering, amplification, and antenna matching.

Technical Specifications & Engineering

To minimize signal interference and ensure repeatable accuracy, our fixtures are built to the highest engineering standards:

EMI Shielding – 6-sided enclosures machined from aluminum or conductive materials to isolate the DUT from external noise.
Impedance Matching – Precision-engineered assemblies that maintain signal integrity across high frequencies.
Premium Materials – Constructed using high-frequency Rogers PCB materials and gold-plated contacts.
Interconnects – Utilizing microstrip or coplanar waveguide lines (CPW) to minimize signal loss.

Key Components

RF Launchers – Specialized connectors (SMA, BNC, N, or SMB) that "launch" the signal into the fixture via coaxial center pins.
DUT Interface (The "Nest") – A custom-designed nest using spring-loaded pogo pins or gold-plated contacts for a consistent, non-destructive connection.
Universal Flexibility – Features exchangeable RF EMI-shielded units to accommodate a wide variety of testing requirements.
