Description

This 25cm RP-SMA female to IPEX1 connector cable is a critical RF accessory for bridging the gap between internal wireless module antenna pads and external, high-gain antennas. The RG1.13 coaxial cable offers a balance of flexibility and low signal attenuation, making it suitable for routing within tight electronic enclosures common in IoT prototypes and embedded systems.

The RP-SMA female connector is the standard reverse-polarity interface found on many consumer routers and external antennas, while the IPEX1 (also known as U.FL) micro-coaxial connector is the de-facto standard for surface-mount antenna connections on compact wireless modules like ESP32, nRF52840, SIM800, and LoRa transceivers. This pigtail ensures proper 50-ohm impedance matching for optimal RF power transfer and minimal VSWR.

Key Features

  • Enables external antenna connectivity for embedded wireless modules with IPEX1/U.FL pads.
  • RG1.13 coaxial cable provides excellent flexibility for tight installation spaces.
  • RP-SMA female connector mates with standard RP-SMA male antennas.
  • IPEX1 (U.FL) connector offers a reliable, click-lock connection to module antenna ports.
  • 25cm length allows for strategic antenna placement to improve signal strength and range.
  • Low-profile 13mm threaded connector ensures a secure mechanical connection.
  • Maintains 50-ohm characteristic impedance for minimal RF signal reflection.
  • Essential for development, testing, and deployment of Wi-Fi, Bluetooth, cellular, and LoRa IoT nodes.

Applications

  • Connecting external antennas to ESP32, ESP8266, or Raspberry Pi Pico W development boards.
  • Adding a high-gain antenna to 4G LTE (SIM7600, SIM800) or NB-IoT modules for improved cellular reception.
  • Extending the range of LoRa (SX1276, SX1262) or sub-1GHz RF nodes in remote sensor networks.
  • Providing antenna diversity or relocating the antenna in compact IoT product designs.
  • Prototyping and testing wireless signal strength with different antenna types (dipole, monopole, panel).

Frequently Asked Questions

What modules is this RP-SMA to IPEX1 cable compatible with?

This cable is universally compatible with any wireless module featuring a surface-mount IPEX1 (U.FL) antenna pad. This includes popular IoT boards like ESP32, ESP8266, nRF52840 BLE modules, SIMCom 4G/LTE modules (SIM7600, SIM800), and LoRa transceivers (SX1276, SX1262). Simply connect the IPEX1 end to the module's antenna port and the RP-SMA female end to your chosen RP-SMA male antenna to significantly improve wireless range and signal reliability.

How do I properly install and route this antenna cable?

First, carefully click the IPEX1 connector onto the module's antenna port, ensuring a secure snap. Route the flexible RG1.13 cable away from noisy digital circuits and power supplies to minimize interference. Use cable ties or adhesive clips to secure the cable, avoiding sharp bends that could damage the internal coax. Finally, screw the RP-SMA female connector onto your external antenna's RP-SMA male base hand-tight. For optimal performance, position the antenna vertically and in clear line-of-sight when possible.

What is the difference between RP-SMA and standard SMA connectors?

RP-SMA (Reverse Polarity SMA) reverses the gender of the inner contact compared to standard SMA. In an RP-SMA female connector, the center pin is hollow (female), while the standard SMA female has a solid center pin (male). This cable uses an RP-SMA female end, designed to mate with RP-SMA male antennas commonly supplied with Wi-Fi routers and aftermarket antennas. Always verify your antenna's connector type to ensure compatibility, as mismatching SMA and RP-SMA can damage the connectors.
