The ROSNOL AD-S2S25A/11-11 is a precision RF adapter engineered for DC to 4 GHz operation with impedance 50 Ω, VSWR ≤ 1.35, and insertion loss ≤ 0.1 × √F(GHz) dB. It provides insulation resistance ≥ 1 GΩ, center contact resistance ≤ 5 mΩ, outer contact resistance ≤ 2.5 mΩ, test voltage 750 V rms, working voltage ≤ 250 V rms, and RF leakage ≥ 55 dB up to 1 GHz. Contact current: 1.5 A DC typical. The snap-lock coupling ensures secure retention and mechanical durability of ≥ 500 mating cycles. Engagement force ≤ 63 N; disengagement force 8 N to 63 N. Temperature range: −65 °C to +155 °C.Centre contacts are brass gold plated (nickel underplated). Body and coupling nut are brass gold plated (nickel underplated). Insulator PTFE. This construction ensures excellent durability and stable electrical performance across the specified frequency range.
ROSNOL’s precision-engineered RF adapters deliver consistent quality and performance at competitive pricing, making them a reliable alternative to leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH. Customization services for materials, plating, and mechanical design are available.
