Description

This 50cm RP-SMA female to IPEX4 connector cable is a critical RF interconnect for system integrators and embedded developers needing to route signals from an internal wireless module’s miniature IPEX4 port to an externally accessible RP-SMA antenna jack. The RG0.81 coaxial construction provides a balanced 50-ohm impedance, minimizing VSWR and signal loss across common IoT frequency bands from 700MHz to 6GHz.

The reverse-polarity SMA (RP-SMA) female connector is the standard interface for many consumer Wi-Fi routers, cellular gateways, and external antenna mounts, while the IPEX4 (often referred to as U.FL) male plug mates with the ultra-compact surface-mount sockets found on ESP32-S3, SIM7600G, RA-02 LoRa, and Quectel BG77 modules. The 11mm connector length and flexible cable allow for clean routing within tight enclosures without stressing the solder joints on the module.

Key Features

  • RP-SMA female to IPEX4 (U.FL) male coaxial pigtail cable for internal-to-external antenna routing.
  • 50cm length RG0.81 cable with 50-ohm impedance for minimal signal attenuation.
  • Compatible with 5G NR, 4G LTE, 3G, GSM, Wi-Fi 2.4/5/6 GHz, Bluetooth, LoRa, and GNSS frequency bands.
  • IPEX4 connector features a secure snap-lock mechanism for vibration-resistant connections on mobile or industrial devices.
  • RP-SMA female interface allows connection to standard external antennas with RP-SMA male plugs.
  • Flexible cable jacket enables clean cable management inside IoT gateways, routers, drones, and telemetry units.

Applications

  • Extending internal cellular module antennas (Quectel, SIMCom) to external magnetic mount antennas on vehicles or industrial enclosures.
  • Connecting ESP32-WROOM or Raspberry Pi CM4 Wi-Fi/BT module IPEX ports to RP-SMA panel mount antennas on smart home hubs.
  • Routing LoRa (SX1276/SX1262) signals from a compact node PCB to a high-gain outdoor antenna with an RP-SMA connector.
  • Providing a test lead for RF performance validation of 5G NR, Wi-Fi 6E, or GPS/GNSS modules during prototype development.

Frequently Asked Questions

What is the impedance of this RP-SMA to IPEX4 cable, and why is it important?

This cable uses RG0.81 coaxial construction with a characteristic impedance of 50 ohms, which is the standard for most RF systems including Wi-Fi, cellular, and GPS. Matching impedance minimizes signal reflections (VSWR) and power loss, ensuring maximum RF power transfer between your wireless module and the external antenna for optimal range and data integrity.

Can I use this cable to connect an ESP32's internal IPEX connector to an external Wi-Fi antenna?

Yes, this cable is designed for that exact purpose. The IPEX4 (U.FL) male plug securely connects to the ESP32-WROOM module's surface-mount antenna port. The RP-SMA female end then attaches to any standard RP-SMA male antenna, allowing you to upgrade to a high-gain directional or omnidirectional antenna to extend Wi-Fi or Bluetooth range in your IoT deployment.

Is this cable suitable for 5G NR or Wi-Fi 6E applications up to 6GHz?

Yes, the RG0.81 cable and connectors are rated for frequencies up to 6 GHz, covering the C-band (3.3-4.2 GHz) and 5 GHz/6 GHz unlicensed bands used by 5G NR and Wi-Fi 6E. Ensure your connected antenna is also rated for these higher frequencies to maintain system performance and avoid excessive attenuation.
