Description
SMA Plug (Male) to SMA Jack (Female) RF Adapter | Screw-lock | Brass Body
The ROSNOL ASL-A1A25A_1.2/911-91 is a compact SMA plug to jack L-adapter supporting frequencies up to 18 GHz. It features a 50Ω impedance and VSWR ≤ 1.2 (≥ 20.8 dB), with insertion loss ≤ 0.04 × √F (GHz) dB. RF leakage is rated ≥ 100 dB up to 1 GHz, and power handling reaches 200 W at 2 GHz. Mechanical performance includes ≥ 500 mating cycles, axial captivation ≥ 17 Ncm, and torque range of 0.8–1.1 Nm. The adapter operates from −65°C to +165°C and meets MIL-STD-202 standards.Both ends use beryllium copper center contacts with gold plating over nickel underplating. The brass body and coupling nut are gold-plated, with PTFE insulators and silicone rubber gaskets for sealing.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment.
