Description

This RP-SMA female to IPEX1 pigtail cable is a critical RF interconnect for developers integrating wireless communication modules into final products. The RG1.13 coaxial cable maintains a consistent 50-ohm impedance over its 15cm length, preserving signal integrity for frequencies used in 5G, 4G LTE, Wi-Fi, and LoRaWAN applications. The reverse-polarity SMA female connector prevents mating with standard SMA antennas, a common compliance feature for consumer wireless equipment.

The IPEX1 (also known as U.FL) connector is a miniature, push-on interface found on virtually all compact wireless modules from ESP32-based boards to Quectel/SIMCom cellular modems and u-blox GNSS receivers. This cable enables the transition from this fragile onboard connector to a robust, threaded RP-SMA port, allowing for the use of larger, higher-gain external antennas to significantly improve wireless range and reliability in IoT deployments.

Key Features

  • Facilitates connection between internal IPEX1 module ports and external RP-SMA antenna systems.
  • Reverse Polarity SMA (RP-SMA) female connector features external threads and a center socket, common in Wi-Fi routers.
  • RG1.13 coaxial cable provides good shielding and low signal loss for high-frequency RF applications.
  • 15cm length offers optimal flexibility for routing within compact IoT device enclosures and control boxes.
  • Standard 50-ohm impedance matching ensures maximum power transfer between the module and antenna.
  • Essential for prototyping and final product builds using ESP32, cellular (4G/5G), LoRa, and Wi-Fi modules with IPEX1 footprints.

Applications

  • Extending antenna connectivity for embedded 4G LTE Cat-1/Cat-M/NB-IoT and 5G cellular modules in IoT gateways.
  • Connecting Wi-Fi/Bluetooth combo modules (ESP32, ESP8266) to external RP-SMA antennas for improved range.
  • Providing a durable antenna port for LoRa/LoRaWAN transceiver modules (RAK3172, E22) with IPEX1 connectors.
  • Integrating GNSS/GPS receivers (u-blox, Quectel) with active external antennas for high-precision tracking.
  • General-purpose RF interconnection in drones, robotics, industrial telemetry, and smart home control panels.

Frequently Asked Questions

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

The gender and polarity are reversed. An RP-SMA female connector has external threads and a center socket (pin receptacle), whereas a standard SMA female has internal threads and a center pin. This design prevents accidental connection of high-gain external antennas to devices that are regulatory certified only with their internal antenna. Always verify your equipment's connector type before purchasing a cable.

How do I securely connect the IPEX1 (U.FL) end to my wireless module?

Align the IPEX1 connector squarely over the module's gold-plated socket. Apply gentle, even pressure straight down until you hear or feel a faint click, indicating the locking clip has engaged. Do not pull on the cable to disconnect. Instead, use a spudger or carefully lift the plastic locking clip on the connector's side before pulling straight up. Repeated improper removal can damage the tiny socket on the module.

Can this cable be used for 5.8GHz Wi-Fi or 5G NR frequencies?

Yes, the RG1.13 cable is suitable for frequencies up to several GHz, covering 2.4GHz & 5.8GHz Wi-Fi, 4G LTE bands, and lower 5G NR frequencies. For optimal performance at higher 5G mmWave frequencies, a lower-loss cable type like RG316 might be preferred. Ensure your external antenna is tuned for the specific frequency band you intend to use for maximum efficiency and minimal VSWR.
