Description

This RP-SMA female to IPEX4 connector cable is a critical RF interconnect for wireless IoT development and deployment. It enables you to connect a high-gain external antenna with an RP-SMA interface directly to the miniature IPEX4 port found on most compact Wi-Fi, Bluetooth, cellular (4G/5G), and GNSS modules. The 20cm RG0.81 coaxial cable provides sufficient length for flexible installation inside project enclosures, helping to position the antenna for best reception while minimizing signal loss.

The cable assembly is engineered for 50-ohm impedance matching, which is standard for most wireless communication systems. Using this pigtail ensures a reliable, low-VSWR connection between your wireless module and antenna, which is crucial for maximizing RF performance, range, and data throughput in applications from LoRaWAN gateways to 4G routers and high-speed Wi-Fi access points.

Key Features

  • Direct interface conversion from external RP-SMA antenna ports to internal module IPEX4 connections.
  • RG0.81 coaxial cable with 50-ohm impedance for minimal signal reflection and loss.
  • 20cm length offers installation flexibility for optimal antenna positioning within device enclosures.
  • IPEX4 connector is a standard for compact Wi-Fi, Bluetooth, cellular, and GPS modules.
  • RP-SMA female connector is compatible with a vast range of aftermarket antennas.
  • Essential for bypassing integrated PCB antennas for improved range and signal reliability.

Applications

  • Connecting external antennas to embedded Wi-Fi/Bluetooth SoC development boards (ESP32, ESP8266).
  • Adding an external antenna to 4G LTE or 5G cellular modems (SIMCom, Quectel modules).
  • Improving GPS/GNSS receiver signal strength in asset trackers and telemetry devices.
  • Extending range for LoRa/LoRaWAN gateway and node RF modules.
  • General-purpose RF interconnection in wireless router, access point, and IoT gateway builds.

Frequently Asked Questions

What modules is this RP-SMA to IPEX4 cable compatible with?

This cable is compatible with any wireless module featuring an IPEX4 (also known as U.FL) socket. This includes common Wi-Fi/Bluetooth SoCs like the ESP32 and ESP8266, many 4G LTE modules from Quectel and SIMCom, GPS/GNSS receivers, and LoRa transceivers. The RP-SMA female end connects to a vast array of standard external antennas with RP-SMA male connectors.

How do I properly install and secure the IPEX4 connector?

Align the IPEX4 connector carefully with the socket on your module, ensuring the center pin is straight. Press down firmly until you hear or feel a distinct click, indicating it is fully seated. Avoid pulling on the cable to disconnect; always grip the connector's plastic body to unplug. For strain relief in permanent installations, use adhesive cable clips or zip-ties to secure the RG0.81 cable near the connector.

What is the impedance of this cable, and why is it important?

This RG0.81 coaxial cable is designed for 50-ohm impedance, which is the standard for most Wi-Fi, cellular, and GPS RF systems. Matching impedance between the antenna, cable, and module's RF port minimizes signal reflection (high VSWR) and power loss. Using a 50-ohm cable ensures maximum power transfer and preserves signal integrity, which is critical for achieving the best possible wireless range and data reliability.
