Product Introduction:
As wireless communications, radar systems, and high-speed data networks push deep into millimeter-wave frequencies, test and measurement setups face unprecedented challenges. At frequencies reaching 67 GHz, minor mechanical movement, temperature variations, and cable flexing can introduce severe phase shift, insertion loss spikes, and calibration degradation.
Our 1.85mm Amplitude- and Phase-Stable Armored Test Cable Series is meticulously engineered for ultra-high-frequency environments up to 67 GHz. Utilizing low-density microporous PTFE dielectrics, advanced outer shielding composites, and heavy-duty stainless steel armoring, these cables deliver exceptional phase and amplitude stability under flexure while protecting delicate precision interfaces on expensive VNA test ports.

At 67 GHz, even sub-millimeter physical shifts translate into noticeable electrical phase errors. Our specialized winding techniques and low-expansion dielectric cores ensure exceptional phase tracking (±5.0° typical at 67 GHz) under normal test flexing, safeguarding your calibration accuracy.
Millimeter-wave test cables are delicate and expensive investments. Our crush-resistant stainless steel armor absorbs external impacts, crushing forces, and accidental pulls, shielding the fragile inner coaxial core without degrading high-frequency mode suppression.
The precision air-dielectric 1.85mm connector interface is designed to mate perfectly with high-frequency network analyzers and calibration modules, ensuring thousands of repeatable connections with minimal wear on connector pins.
