Description

This SMA Female to IPEX4 connector cable is a critical RF accessory for connecting external high-gain antennas to the compact IPEX4 (MHF4) RF pads found on most modern wireless communication modules. The 50cm RG0.81 coaxial cable offers a balance between flexibility and signal integrity, with a characteristic impedance of 50 ohms to match standard RF systems.

Designed for integration into tight spaces, the cable enables developers to relocate antennas for better signal reception in IoT gateways, routers, trackers, and embedded systems using ESP32, nRF52, Quectel, or SIMCom modules. The SMA Female connector mates with standard SMA male antenna plugs, while the IPEX4 end provides a secure, click-lock connection to module footprints, ensuring a stable RF path for 2G/3G/4G/5G, Wi-Fi, Bluetooth, LoRa, and GPS/GNSS applications.

Key Features

  • Direct interface from standard SMA antenna ports to miniature IPEX4 module connectors.
  • RG0.81 coaxial cable (50-ohm impedance) supports frequencies up to 6 GHz with low signal attenuation.
  • 50cm length allows for strategic antenna placement to improve wireless link budget and reduce interference.
  • IPEX4 connector with 11mm housing ensures a positive lock and strain relief on the module side.
  • SMA Female connector (Jack) provides a robust, threaded interface for a wide variety of external antennas.
  • Flexible cable routing ideal for internal mounting within product enclosures and prototypes.
  • Essential for upgrading or extending the RF performance of development boards and commercial modules.

Applications

  • Extending antenna connectivity for ESP32, ESP8266, Raspberry Pi, and other SBC Wi-Fi/Bluetooth boards.
  • Connecting external high-gain antennas to 4G LTE, 5G, or NB-IoT cellular modules (e.g., SIM7600, EC25).
  • Routing GPS/GNSS active antenna signals to compact tracking and telematics devices.
  • Providing antenna flexibility in LoRaWAN gateways and sensor nodes using IPEX-based RF modules.
  • Internal cabling for IoT routers, industrial gateways, and smart home hubs requiring optimized RF placement.

Frequently Asked Questions

What modules is this SMA to IPEX4 cable compatible with?

This cable is compatible with any wireless module featuring an IPEX4 (MHF4) RF connector pad. This includes common Wi-Fi/Bluetooth SoCs like the ESP32-S3 and nRF52840, cellular modules such as the SIM7600G-H and EG25-G, LoRa transceivers like the SX1276, and many GNSS receivers. The SMA Female end connects to standard SMA male antennas, making it a universal adapter for upgrading onboard antenna performance in embedded designs.

What is the maximum frequency and power rating for the RG0.81 cable?

The RG0.81 coaxial cable is rated for frequencies up to 6 GHz, covering Wi-Fi 6E, 5G sub-6 GHz bands, and standard GNSS/GPS signals. Its 50-ohm impedance matches standard RF systems. While specific power handling depends on length and frequency, RG0.81 is suitable for typical low-power IoT applications with transmit powers under 1 Watt. For high-power RF links, verify the cable's attenuation spec or consider a thicker coax variant like RG174 or RG316.

How do I securely attach the IPEX4 connector to my module?

Align the IPEX4 plug with the module's surface-mount connector, ensuring the metal shield clips are oriented correctly. Gently press down until you hear or feel a distinct click, indicating the center pin is engaged and the outer clips have locked. Avoid bending the cable sharply at the connector junction. For strain relief, use adhesive cable clips or a small dab of non-conductive silicone to secure the cable to the PCB, preventing stress on the solder joints during movement or vibration.
