Description

This SMA Female to IPEX4 connector cable is a critical RF accessory for wireless system integration. The RG0.81 miniature coaxial cable provides a balanced compromise between flexibility and low attenuation, maintaining signal integrity for frequencies up to several GHz. The 30cm length offers practical routing flexibility inside device enclosures, allowing optimal antenna positioning away from potential sources of interference.

The SMA female connector is the industry-standard threaded interface for external antennas, while the IPEX4 (often referred to as U.FL) is the dominant ultra-miniature connector for on-board wireless modules from ESP32, nRF52, Quectel, and Semtech families. This pigtail ensures a 50-ohm impedance-matched path, minimizing VSWR and preserving RF power transfer between the module and the antenna for maximum range and data reliability.

Key Features

  • Provides a direct, impedance-matched RF link between SMA antenna ports and IPEX4 module connectors.
  • RG0.81 coaxial cable construction ensures minimal signal loss and stable performance across common IoT frequency bands.
  • 30cm length allows for flexible antenna placement to optimize signal reception and transmission within a device.
  • SMA female connector features a standard threaded coupling nut for a secure, vibration-resistant connection to antennas.
  • IPEX4 plug is designed for compact PCBs, enabling easy connection to wireless modules without soldering.
  • Essential for prototyping and final product assembly involving Wi-Fi, cellular, LoRa, or GPS/GNSS modules.

Applications

  • Connecting external SMA antennas to embedded Wi-Fi/Bluetooth SoC modules (ESP32, ESP8266, nRF52840).
  • Linking 4G LTE or 5G cellular modem boards (Quectel, SIMCom) to roof-mounted or external cellular antennas.
  • Providing a feedline for LoRa/LoRaWAN node modules (RAK, Dragino) to a dedicated LoRa antenna.
  • Routing GPS/GNSS signals from an active patch antenna to a compact GNSS receiver module.
  • General-purpose RF interconnection in IoT gateways, routers, and wireless sensor prototypes.

Frequently Asked Questions

What modules is this SMA to IPEX4 cable compatible with?

This cable is compatible with any wireless module featuring an IPEX4 (U.FL) socket. This includes common Wi-Fi/Bluetooth SoCs like the ESP32 and ESP8266 series, nRF52 BLE modules, 4G LTE modules from Quectel (EC25, EG25) and SIMCom (SIM7600), LoRa modules like the RAK3172 or SX1276/SX1262 boards, and many GPS/GNSS receivers. Ensure your module has a male IPEX4 connector pad.

How do I properly connect the IPEX4 end to my module?

Align the IPEX4 connector carefully with the socket on your module. The connector has a center pin and an outer shield. Apply gentle, straight-down pressure until you hear or feel a faint click, indicating it is fully seated. Do not pull on the cable to disconnect; use a dedicated U.FL removal tool or carefully rock the connector sideways to release the latch. Forcing it can damage the fragile socket on the module.

Is this cable suitable for 5.8GHz Wi-Fi or other high-frequency applications?

While RG0.81 cable is used for many RF applications, its performance at higher frequencies like 5.8GHz may involve increased attenuation compared to specialized low-loss cables. For short 30cm runs in typical IoT or prototyping scenarios, it is generally acceptable. For critical high-frequency or long-distance links, verify the cable's datasheet for specific insertion loss figures at your target frequency.
