The RUC 2.92mm female to N-Type female coaxial adapter is designed for reliable interconnections in VNA configurations and RF/microwave test systems. With a specified frequency range from DC to 18 GHz, 50 Ω impedance, VSWR ≤1.15 and insertion loss ≤0.15 dB, it supports stable measurement setups where low reflections and robust connections between instrumentation and fixtures are required. Its passivated stainless steel construction, with gold-plated BeCu center contact and ≥500 mating cycles, makes it suitable for repeated use in laboratory, R&D and RF validation environments.
