Description
SMA PCB Connector | End Launch | Brass Body
The ROSNOL SMA2H3B50-0090A/91 is a precision SMA Jack (female) engineered for PCB end launch applications. It utilizes a screw-lock coupling mechanism rated for at least 500 mating cycles, providing reliable and repeatable connections. Supporting frequencies from DC to 18 GHz with a 50 Ω impedance, this connector ensures optimal signal transmission with VSWR ≤1.20 up to 6 GHz and ≤1.30 up to 18 GHz, and insertion loss ≤ 0.03 × √F (GHz) dB. The flat coaxial pin is air-insulated with PTFE for enhanced signal integrity.The SMA2H3B50-0090A/91 features a brass body and beryllium copper center contact, both finished with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus underplating. Designed for end launch mounting, it meets MIL-STD environmental standards for vibration, shock, and moisture resistance.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
