SMA Jack (Female) to Precision TNC Jack (Female) RF Adapter | Screw-On | Gold-Plated SMA Body
The ROSNOL AD-A2PCT25B/91-94 is a precision 50Ω RF adapter designed to connect SMA Jack (Female) and Precision TNC Jack (Female) interfaces. Supporting frequencies from DC to 18 GHz, this high-performance adapter delivers VSWR ≤ 1.25, insertion loss ≤ 0.1 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, and a working voltage of 480 V rms. Its low-reflection design helps maintain signal integrity across demanding RF and microwave applications. Material construction includes beryllium copper center contacts with gold plating over a non-magnetic nickel-phosphorus underplating. The SMA body is gold plated, while the Precision TNC body features a copper-tin-zinc alloy finish for reliable conductivity and corrosion resistance. Ideal for aerospace, defense, wireless communications, microwave instrumentation, laboratory testing, and precision RF measurement systems. It provides stable high-frequency performance, excellent mating durability, and dependable interconnection between SMA and Precision TNC interfaces.
