RG405 50 Ohm MIL-DTL-17 Complaint Cable 0.086" Semi-Rigid Cable 20GHz VNA Test Cable

When board space is measured in millimeters and frequencies push past 20 GHz, RG405 M17/133 delivers where flexible cables cannot go. This 0.086 inch semi-rigid coaxial cable packs mil-spec microwave performance into a 2.2mm diameter copper tube, making it the go-to choice for dense phased arrays, compact test fixtures, and satellite payloads where every millimeter matters. The seamless copper outer conductor acts as both shield and structural element, maintaining precise 50 Ohm geometry through 20 GHz while protecting the 1/0.51mm SCCS center conductor from mechanical stress. Engineers specify RG405 when they need predictable phase length in temperature-cycling environments and cannot tolerate the signal leakage inherent in braided constructions.
