rf adapter & cable assemblyProduct Overview
The SMA-KKG is a straight female-to-female coaxial adapter engineered for precision RF and microwave interconnection. As an 18GHz SMA Female to Female High Frequency Test RF Adapter, it enables seamless inline coupling of two SMA male-terminated cables or devices.
The adapter body is machined from high-grade stainless steel for superior corrosion resistance and mechanical stability, while the inner conductor is crafted from beryllium copper with gold-plated contact surfaces to minimize insertion loss.
PTFE dielectric supports consistent 50-ohm impedance from DC to 18 GHz, and the durable construction withstands over 500 mating cycles in repeated test bench use.
