YILIANDUO 1.85mm Male Female Precision RF Adapter DC-67GHz 50 Ohm Stainless Steel Millimeter Wave Test Connector VSWR ≤1.25

Our YILIANDUO 1.85mm male female precision RF adapter is a professional 50 Ohm straight in-line millimeter wave connector rated DC to 67GHz, built for high-frequency RF test and measurement systems. Manufactured with passivated stainless steel body, this 1.85mm FF coaxial adapter delivers ultra-low insertion loss ≤0.05dB and maximum VSWR 1:1.25, eliminating signal reflection and loss for accurate VNA, microwave and mmWave signal testing.

Designed exclusively for millimeter-wave high-frequency applications, this precision RF test connector solves unstable signal transmission issues common in low-grade adapters. The passivation anti-corrosion treatment prevents secondary oxidation, extending service life under long-term lab, aerospace, telecom and radar operation. We provide full series options: Female to Female, Male to Female, Male to Male 1.85mm adapters to match all your RF equipment interconnection demands, widely adopted by electronic manufacturers, university labs, aerospace institutes, 5G base station developers and automotive radar R&D teams.
