Description
SMA Jack (Female) to SMA Jack (Female) | Straight Design | Screw-Lock | Brass Body with Copper-Tin-Zinc Alloy Finish
The ROSNOL AD-A2A25A/94-94 is a straight SMA jack-to-jack adapter optimized for DC to 18 GHz with 50 Ω impedance. It achieves VSWR ≤ 1.20 (Return Loss ≥ 20.8 dB), insertion loss ≤ 0.05 × √f (GHz), insulation resistance ≥ 5 GΩ, center contact resistance ≤ 3 mΩ, outer contact resistance ≤ 2 mΩ, test voltage 1000 V rms, working voltage 480 V rms, and power handling up to 200 W at 2 GHz. RF leakage is rated at ≥ 100 dB up to 1 GHz. The screw-lock mechanism ensures axial center-contact captivation ≥ 27 N, radial captivation ≥ 3 N·cm, and mechanical endurance of ≥ 500 mating cycles, with recommended torque 0.8–1.1 Nm.Piece parts and plating: center contact in beryllium copper with gold plating over non-magnetic nickel-phosphorus underplating; body in brass with copper-tin-zinc alloy finish; PTFE insulator. The design supports operation from −65 °C to +155 °C and provides superior corrosion resistance.
ROSNOL’s precision-engineered RF adapters deliver dependable performance for RF and microwave systems. Built under ISO 9001-certified processes and fully compliant with RoHS and REACH, ROSNOL offers high quality at competitive pricing as an effective alternative to major global brands. Customization services for plating, materials, and mechanical design are available.
