SMA Adapter Straight Barrel SMA-F/F 50 Ohm Coupler Arduino WiFi

SMA Adapter Straight Barrel SMA-F/F 50 Ohm

Straight adapter with two SMA female (SMA-F) jacks, commonly called a barrel. The coupler joins two cables or devices terminated with SMA male plugs. The connector has 50 Ohm impedance, the standard in radio communications and wireless networks. It works well in projects that require extending an antenna feed line. It is widely used with ESP8266, ESP32, Arduino, and Raspberry Pi modules.

Key technical specifications

• Connector type: SMA female (SMA-F) on both sides
• Construction: Straight
• Type: Adapter (barrel)
• Characteristic impedance: 50 Ohm
• Application: Radio frequency (RF), WiFi

Example applications

• Extending antenna cables in wireless WiFi installations
• Connecting communication modules to external antennas for ESP8266, ESP32, Arduino, and Raspberry Pi
• Modifying and upgrading amateur radio and radio communication equipment
• Service and diagnostics of wireless data transmission systems
• Integrating transmitters and receivers with antenna infrastructure
• Building coherent signal bridges in RF measurement circuits

Main benefits

• Lets you quickly and securely join two SMA plugs without replacing the whole cable
• Reduces signal loss and interference by maintaining standard 50 Ohm impedance
• High compatibility with popular kits for ESP8266, ESP32, Arduino, and Raspberry Pi
• Solid metal construction for stable mechanical connection
• Easy to disconnect and rework transmission paths as your project changes
