High-Performance RF Connectivity Solutions for Test and Measurement

In high-frequency testing, connector performance is often the weakest link, introducing measurement uncertainty across 5G/6G, SATCOM and DataCom systems. Test engineers require interconnect solutions that maintain consistent signal integrity as equipment moves from the lab to the field. Molex delivers precision RF connectors and ruggedized cable assemblies engineered to support accurate, repeatable testing in the most demanding test environments.

Overcoming RF Connectivity Challenges in Test and Measurement


At high frequencies, connectors emerge as a common source of measurement error. Engineers routinely contend with insertion loss, phase instability and wear-related repeatability issues that compromise accuracy over time. In high-cycle and automated test setups, these effects are amplified, often forcing teams to spend valuable debug time determining whether anomalies originate in the device under test (DUT) or from connector degradation. Differences in connector strategies across lab, manufacturing and field environments further complicate correlation and validation workflows.

Addressing these challenges requires interconnect solutions designed explicitly for the rigors of RF test and measurement. High-performance connectors with low insertion loss and phase stability under flexure are essential to mitigating signal degradation at mmWave frequencies. Equally important are calibration practices that establish the reference plane at the connector interface leveraging SOLT, TRL or ECal techniques to de-embed the test setup and isolate the DUT performance. When combined with disciplined inspection, cleaning and lifecycle tracking, these approaches minimize measurement uncertainty and support repeatable, trustworthy results.

Molex applies lifecycle management and application-driven calibration practices to help engineers achieve consistent signal integrity across test environments. Tight mechanical tolerances and optimized connector designs mitigate loss and phase instability, while proactive maintenance and mating-cycle control reduce wear-related variability. By aligning calibration methods to real connector interfaces, Molex solutions improve efficiency in lab-to-production workflows and build greater confidence in RF test accuracy.

Optimizing Signal Integrity Across the mmWave Spectrum

At mmWave and wideband frequencies, connectors can introduce signal degradation that limits measurement accuracy and overall system performance. High-frequency test environments require connector interfaces that maintain low insertion loss, stable return loss and consistent repeatability so DUT behavior is measured with confidence.

Molex addresses these demands with precision RF connectors and cable assemblies, including the Cardinal series, engineered to deliver stable performance up to 145 GHz.

Maintaining RF Performance in Extreme Environments

In high-stress lab and field environments, connectors and cable assemblies can fail prematurely, leading to unexpected downtime and compromised testing reliability. These conditions demand robust interconnect solutions designed to withstand vibration, temperature extremes and repeated handling without degrading electrical performance.

Molex meets this need with ruggedized RF connectors and custom-armored Cardinal Test High-Frequency Cable Assemblies, engineered for extended service life and dependable operation in demanding environments.

Ensuring Data Correlation in Lab and Field Testing

When connector strategies differ between lab, manufacturing and field environments, measurement data can become difficult to correlate, slowing product validation cycles. Accurate correlation requires a standardized connector and reference-plane approach supported by consistent interface selection, calibration practices and lifecycle control.

Molex precision cables and adaptors enable aligned connector strategies across environments, improving measurement consistency and accelerating time-to-market.
