Radio Frequency Fixtures

High-attenuation RF test fixtures and shielded enclosures engineered for reliable, interference-free wireless testing across cellular, Wi-Fi, Bluetooth, and radar frequencies.

Radio Frequency (RF) Test Fixtures & Shielded Enclosures

Engineered for optimal impedance matching and low-loss signal propagation, these high-attenuation RF chambers—spanning from compact benchtop test cells to pneumatic, production-grade enclosures—guarantee precise wireless validation without external interference.

Our RF test platforms provide a fully shielded, EMI-isolated environment that establishes a non-destructive bridge between your Device Under Test (DUT) and high-frequency instrumentation, such as Vector Network Analyzers (VNAs) and spectrum analyzers. They enable real-time RF parametric monitoring and power measurements while preserving signal purity and preventing stray interference from corrupting test data.

Key Testing Applications & Functions

Fixtronic RF interface systems are vital for evaluating, tuning, and verifying wireless hardware across all stages of production:

  • Parametric Signal Analysis

    Accurate capture of RF output power, frequency accuracy, impedance curves, noise figures, and spectral purity.

  • Transceiver & Signal Processing Verification

    Facilitates continuous monitoring of RF modulation, demodulation fidelity, and baseband signal synthesis.

  • Circuit & Antenna Tuning

    Ideal for verifying filter attenuation, power amplifier linearity, matching network performance, and antenna radiation patterns.

To eliminate electromagnetic leakage and ensure repeatable measurement cycles, every Fixtronic RF fixture is crafted to rigid RF standards:

  • High-Attenuation EMI Isolation

    Six-sided Faraday cages CNC-machined from solid aluminum alloys or conductive composites, offering deep decibel isolation from ambient cellular, Wi-Fi, and industrial noise.

  • Impedance-Matched Routing

    Custom trace geometry and low-loss transmission paths engineered to prevent standing waves and signal reflection at gigahertz frequencies.

  • RF-Grade Materials

    Manufactured using low-dielectric Rogers laminate substrates, beryllium-copper contacts, and heavy gold plating for long-term wear resistance.

Core Hardware Components

  • Precision RF Launchers

    High-frequency coaxial transitions (SMA, 2.92mm, 2.4mm, N-type, or SMB) designed to transition RF energy into the fixture matrix with minimal insertion loss.

  • Custom DUT Nesting

    Custom-milled alignment nests fitted with non-magnetic, gold-plated spring probes that establish a gentle, highly repeatable contact profile with the target PCBA.

  • Exchangeable Shielded Cassettes

    Interchangeable RF-shielded cassette inserts that allow a single base enclosure to host multiple product variants, minimizing capital tooling costs.

We combine state-of-the-art manufacturing with stringent quality control to ensure smooth test operations, zero false failures, and maximum uptime. By offering our custom engineering solutions at competitive prices and with rapid lead times, we provide the reliable testing infrastructure you need to scale production without compromising your schedule or bottom line.

Partner with us to scale your products with confidence, knowing your testing infrastructure is built to perform.
