FMAD1208 is a precision SMA female to TNC female adapter designed to enable connections between two different connector types in RF and microwave applications. The adapter features a straight body geometry with gold over nickel plated beryllium copper contacts and PTFE insulation, operating across a frequency range up to 18 GHz with excellent VSWR performance of 1.2:1 maximum. The SMA connector mechanically mates with commercially available 3.5mm and 2.92mm (K) connectors, providing versatile compatibility. This precision adapter is ideal for general purpose test applications, precision test and measurement scenarios, and protecting expensive equipment connectors by serving as a replaceable interface during frequent connect and disconnect cycles.
