SMA Jack (Female) to 4.3-10 Jack (Female) Adapter, DC-12GHz VSWR 1.15

SMA Jack (Female) to 4.3-10 Jack (Female) RF Adapter | Screw-Lock | Brass Body

The ROSNOL AD-A2431025A/94-94 RF adapter features a straight configuration connecting SMA jack (female) to 4.3-10 jack (female), engineered for high-frequency performance up to 12 GHz with a 50-ohm impedance. It offers superior electrical characteristics, including VSWR ≤ 1.15 (≥ 23 dB return loss), insertion loss ≤ 0.04 × √F (GHz) dB, and RF leakage ≥ 100 dB from DC to 1 GHz. Power handling reaches 200 W at 2 GHz, with insulation resistance ≥ 5 GΩ. Mechanical integrity is ensured through screw-lock coupling mechanisms, axial captivation of ≥ 30 N (4.3-10) and ≥ 20 N (SMA), and recommended torque of 5 Nm and 0.8–1.1 Nm respectively. Mating durability exceeds 100 cycles for 4.3-10 and 500 cycles for SMA.

Constructed from premium materials, the center contacts are beryllium copper with gold plating over a non-magnetic nickel-phosphorus underlayer. The bodies are precision-machined brass with copper-tin-zinc alloy plating, and PTFE insulators provide excellent dielectric performance. This robust design guarantees long-term stability under demanding RF and microwave conditions.

ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
