SMA Female RF Connector – Gold-Plated Crimp Connector for Coaxial Cables up to 6 GHz

This SMA female RF connector (crimp-on type) is designed for installation onto coaxial cables such as RG58 U, LMR195, RG142, and RG400 — all standard 50 Ω RF coax cables. It allows you to build custom RF cable assemblies or replace damaged connectors in antennas, wireless systems and RF test setups.

 Key Features

✔ Type: SMA female RF connector with threaded interface — standard 50 Ω RF connector.
✔ Attachment: Crimp termination — the connector’s ferrule is crimped to the cable’s braid; the centre contact is often soldered to the conductor for a secure electrical connection.
✔ Compatible Cables: RG58 U, LMR195, RG142, RG400 and similar 50 Ω coaxial cables.
✔ Impedance: 50 Ω — standard RF impedance for antennas and wireless applications.
✔ Construction: typically metal body with plated contacts for durability and reduced oxidation.

What It Does:
An SMA connector is a threaded RF coaxial connector, widely used in microwave, wireless and RF communication systems. The female SMA has external threads and accepts the male SMA plug for strong, low-loss RF connections.

 Installation Notes

Proper installation usually involves special crimp tools to compress the connector ferrule onto the cable braid and optional soldering for the centre contact, resulting in better signal transfer and mechanical stability compared to slip-on or screw-on connectors.

 Typical Uses

✔ Wi-Fi, Bluetooth, GSM/LTE, LoRa and RF antennas.
✔ Custom RF cable assemblies and repairs.
✔ Software-defined radio (SDR) and RF test equipment.
✔ Wireless modules and RF hardware connectivity.

 Benefits

• Supports multiple 50 Ω coax types for versatile use.

• Low signal loss and solid connection when correctly installed.

• Reliable mechanical stability using crimp and solder methods.
