Description

This RP-SMA Female to IPEX4 connector cable is a precision RF pigtail designed for interfacing external antennas with modern wireless communication modules. The RG0.81 coaxial cable provides a 50-ohm characteristic impedance, minimizing signal reflection and insertion loss across common IoT frequency bands from sub-GHz LoRa up to 5.8 GHz Wi-Fi. Its 10cm length allows for flexible placement and strain relief in final product enclosures.

The RP-SMA female connector mates with standard RP-SMA male antenna ports commonly found on routers, access points, and gateway enclosures. The opposite end terminates in an IPEX4 (also known as U.FL) plug, the de-facto standard for connecting miniature, board-mounted antennas to compact Wi-Fi, Bluetooth, cellular, and GPS modules. This cable is indispensable for developers and integrators building reliable wireless links where direct PCB antenna soldering is impractical or where antenna diversity and external mounting are required.

Key Features

  • RP-SMA Female to IPEX4 (U.FL) interface for connecting external antennas to compact wireless modules.
  • RG0.81 coaxial cable with 50-ohm impedance ensures minimal VSWR and signal integrity for high-frequency RF.
  • 10cm cable length provides optimal flexibility for routing within device enclosures and prototypes.
  • IPEX4 connector features a secure snap-lock mechanism for reliable, vibration-resistant connections.
  • Compatible with a wide spectrum of wireless technologies including 5G/4G LTE, GNSS, Wi-Fi 2.4/5GHz, Bluetooth, and LoRa.
  • Essential for upgrading or replacing integrated antenna connections on development boards and commercial modules.

Applications

  • Connecting external high-gain antennas to ESP32, ESP8266, or Raspberry Pi Wi-Fi/Bluetooth modules via their IPEX footprints.
  • Providing antenna connectivity for 4G LTE (e.g., SIM7600, SIM800) and 5G cellular modules in IoT gateways and routers.
  • Extending GNSS/GPS antenna placement in asset trackers and telematics devices for improved satellite reception.
  • Enabling antenna diversity or external mounting for LoRaWAN nodes and gateways using SX1276/SX1262 modules.
  • Prototyping and final assembly in consumer electronics, drones, and industrial wireless sensors requiring a reliable RF path.

Frequently Asked Questions

What is the difference between SMA and RP-SMA, and which one does this cable use?

This cable uses an RP-SMA (Reverse Polarity SMA) female connector. In RP-SMA, the gender of the center conductor is reversed compared to standard SMA: the RP-SMA female has a center pin, while the standard SMA female has a center socket. This cable is designed to mate with a standard RP-SMA male antenna port, which is common on many Wi-Fi routers and external antennas. Always verify your device's connector type before purchase to ensure compatibility.

Can I use this cable to connect an antenna directly to an ESP32-DevKitC board?

Yes, if your specific ESP32 development board has a populated IPEX (U.FL) footprint. Many boards like the ESP32-DevKitC do not come with the IPEX connector soldered by default. You would need to solder a surface-mount IPEX socket onto the board's antenna pad. Once installed, this cable can connect an external RP-SMA antenna to that socket, often improving range over the onboard PCB trace antenna. Always ensure the board is powered off when connecting or disconnecting the cable.

Is this cable suitable for 5.8GHz Wi-Fi or 5G cellular antenna connections?

Yes, the RG0.81 coaxial cable is designed for RF applications and supports frequencies commonly used in 5.8 GHz Wi-Fi and sub-6 GHz 5G NR bands. Its 50-ohm impedance and construction aim to minimize signal loss at higher frequencies. For optimal performance in critical 5G applications, ensure your antenna and the cable assembly are rated for the specific frequency band in use, as insertion loss increases with frequency and cable length.
