SMA RF Coaxial Connectors – 50Ω Screw-On PCB Mount SMA Jack

SMA RF coaxial connectors, part of the Sub-Miniature version A family, feature a durable screw-on coupling mechanism and precise 50 Ω impedance. Engineered for performance from DC to 18 GHz (with extended variants up to 26.5 GHz), these connectors are ideal for microwave systems, Wi-Fi applications, radio modules, and test equipment.

Available in both male and female formats, our PCB SMA jacks offer robust mechanical reliability, compact integration, and consistent signal integrity. Constructed with high-quality brass or stainless steel and gold plating, they support up to 500 mating cycles.

Key Features:

• Impedance: 50 Ω

• Screw-on (threaded) coupling for secure, vibration-resistant connections

• Frequency range: DC to 18 GHz (extended up to 26.5 GHz)

• Material: Brass or stainless steel with gold plating for enhanced durability and conductivity

• High mating cycles (≥ 500) for long-term reliability

• Ideal for PCB mounting in compact, high-frequency systems
