Product Introduction:
In precision RF and microwave testing, measurement repeatability is everything. Mechanical flexing, temperature fluctuations, and harsh laboratory or factory floor environments can introduce phase errors, amplitude drift, and premature cable failure—costing valuable engineering time and compromising test accuracy.
Our 3.5mm Amplitude- and Phase-Stable Armored Test Cable Series is specifically designed for demanding test and measurement applications up to 26.5 GHz. Featuring advanced microporous PTFE dielectrics, multi-layer shielding, and rugged stainless steel armoring, these cables deliver exceptional phase and amplitude stability under flexure while withstanding the physical rigors of daily high-frequency testing.

When routing cables around test fixtures or connecting to rotating handlers, phase variation can ruin calibration accuracy. Our proprietary dielectric core and tight-tolerance outer braid construction ensure minimal phase change (±3.0° typical at 26.5 GHz) even after repeated bending.
Laboratory environments are punishing. Dropped tools, heavy foot traffic, and sharp bends can destroy standard flexible cables. Our multi-layer crush-resistant armor absorbs external mechanical shock and torsion while maintaining a tight minimum bend radius.
Fully compatible with SMA and 2.92mm interfaces, our precision 3.5mm connectors feature ruggedized coupling nuts and non-degredation center contacts, ensuring long calibration lifespans and accurate VNA measurements.
