This RF adapter cable bridges the gap between small u.FL board connectors and standard SMA antennas. One end has a panel-mount SMA female connector, the other a u.FL (also known as IPEX, IPAX, IPX, MHF) plug — ideal for connecting external antennas to GPS modules, cellular modules, and other RF boards with u.FL ports.
Key Features
- SMA to u.FL Adapter – Connects SMA antennas to u.FL board connectors
- Panel-Mount SMA – SMA female connector for secure enclosure mounting
- RG178 Cable – Lightweight, flexible coaxial cable
- 15 cm Length – Compact cable (not including SMA connector)
Specifications
- Connector A – SMA female (panel-mount)
- Connector B – u.FL / IPEX / IPX / MHF
- Cable Type – RG178
- Length – 15 cm (5.9")
Ideal For
- GPS and cellular module antenna connections
- LoRa and LPWAN radio projects
- RF prototyping with u.FL-equipped boards
Warning: This cable has an SMA connector, not RP-SMA. Most WiFi routers use RP-SMA — these connectors are not compatible. Check your antenna before ordering.
Jargon buster
Plain-language definitions for the technical terms used above.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- LoRa
- LoRa is a long-range, low-power wireless radio technology often used for telemetry, remote sensors and other links that send small amounts of data over long distances. It is distinct from Bluetooth and WiFi, so sharing a connector or pinout with LoRa hardware does not mean a device actually uses LoRa.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- SMA
- SMA is a small threaded coaxial (RF) connector widely used to attach antennas and other radio-frequency cables. A device with SMA antenna ports needs antennas or pigtails with matching SMA connectors, or a suitable adapter, to connect to them.
- u.FL
- u.FL is a tiny snap-on antenna connector often used on compact wireless boards. A board with u.FL usually needs an external antenna, which matters if the product will be inside an enclosure or needs better antenna placement.
