Description
SMA Plug (Male) to SMA Reverse-Polarity Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-A1A75A/911-91 is a straight RF adapter designed for DC to 18 GHz operation with impedance 50 Ω, VSWR ≤ 1.20, and insertion loss ≤ 0.05 × √F(GHz) dB. It features insulation resistance ≥ 5 GΩ, test voltage 1000 V rms, working voltage 480 V rms, and power handling up to 200 W @ 2 GHz, with RF leakage ≥ 100 dB to 1 GHz. The screw-lock mechanism provides secure coupling, center-contact captivation (axial ≥ 27 N; radial ≥ 3 N·cm), and mechanical endurance of ≥ 500 mating cycles. Temperature range: −65 °C to +155 °C.
Center contact beryllium copper gold plated (3 µin) over non-magnetic nickel-phosphorus underplating (80 µin); body brass gold plated over Ni-P underplating. Insulator PTFE; gasket silicone rubber; coupling nut brass with gold over Ni-P underplating. The multi-layer plating stack provides strong corrosion resistance and consistent RF performance across the specified temperature 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.
