Amphenol SMA Connectors

Amphenol SMA connectors are high-performance, semi-precision 50 Ω coaxial RF interconnects featuring a rugged threaded coupling mechanism that ensures secure, repeatable mating and excellent mechanical durability in demanding environments. Designed for broadband operation from DC to 18 GHz (with extended versions supporting up to 34 GHz), they deliver superior electrical performance, including low VSWR, minimal insertion loss, and outstanding phase stability. Constructed from materials such as stainless steel or brass per MIL-C-39012 standards, with precision-machined components and compatibility with standard, semi-rigid, and flexible cables, these compact connectors are widely trusted in wireless infrastructure, aerospace, radar systems, test and measurement instrumentation, 5G applications, and military electronics where signal integrity and vibration resistance are critical.
