TELEGÄRTNER SMA Male to SMA Male Coaxial Adapter, 50 Ohm, DC-18 GHz, Gold-Plated Brass

RF systems often need a reliable way to join two SMA cables or components with male connectors. This TELEGÄRTNER coaxial adapter provides a straight, in-line connection between two SMA male interfaces, eliminating the need for custom cabling or gender changers in many setups.

Who is it for

Engineers, technicians, and radio amateurs working with RF test equipment, antenna systems, or communication devices up to 18 GHz. It suits laboratories, production lines, and field service where precise impedance matching and low signal loss are critical.

Main features

• Connector 1: SMA male
• Connector 2: SMA male
• Impedance: 50 Ω
• Frequency range: DC to 18 GHz
• VSWR: ≤ 1.25 across the full band
• Body and center contact: gold-plated brass for corrosion resistance and repeatable performance
• Insulator: PTFE for high-temperature stability
• Operating temperature: -65 °C to +165 °C
• Mating cycles: ≥ 500

Specifications

• Adapter type: Coaxial
• Configuration: Straight
• Dielectric withstanding voltage: 1000 Veff
• Insulation resistance: ≥ 5 GΩ
• Center contact resistance: ≤ 2.0 mΩ
• Outer contact resistance: ≤ 2.5 mΩ

Tips

Ensure both mating connectors are clean and properly torqued to achieve the specified VSWR. For outdoor use, protect the connection with weatherproofing tape or a boot, as the adapter itself is not sealed.
