Description

This 50cm RF pigtail cable is engineered for seamless integration between compact wireless modules and standard antenna ports. The cable utilizes RG178 coaxial construction, a 50-ohm impedance-matched design that minimizes signal attenuation and VSWR, ensuring stable power transfer for critical 2.4GHz/5GHz Wi-Fi and Bluetooth links. The IPEX 1 (MHF1) connector is the industry-standard interface for onboard module antenna pads, while the reverse-polarity SMA female end connects to a vast ecosystem of external antennas.

With a slim 11mm connector length and flexible cable body, this assembly is built for reliability in space-constrained applications such as Raspberry Pi HATs, ESP32 development boards, cellular modems, and industrial sensor gateways. It provides a robust mechanical and electrical bridge, eliminating the need for direct soldering and enabling quick antenna swaps or field upgrades.

Key Features

  • Provides a critical interface between internal module IPEX pads and external RP-SMA antennas.
  • RG178 coaxial cable offers a balance of flexibility and low signal loss for short runs.
  • 50-ohm impedance ensures optimal power transfer and minimizes signal reflections.
  • Reverse-polarity SMA (RP-SMA) female connector prevents mating with standard WiFi equipment.
  • Compact 11mm connector profile fits in densely populated PCB layouts.
  • Enhances wireless range and reliability by enabling proper antenna placement.
  • Essential for prototyping, testing, and final integration of wireless IoT devices.

Applications

  • Connecting ESP32, ESP8266, Raspberry Pi, or cellular module IPEX antenna pads to an external antenna.
  • Extending the antenna port on compact Wi-Fi routers, access points, or Bluetooth beacons.
  • Improving signal strength in embedded systems by relocating the antenna outside a metal enclosure.
  • Prototyping and development work on wireless sensor nodes and IoT gateways.

Frequently Asked Questions

What devices is this IPEX to RP-SMA cable compatible with?

This cable is designed for wireless modules and development boards featuring an IPEX 1 (MHF1) antenna pad. It is commonly used with ESP32, ESP8266, nRF52, Raspberry Pi WiFi/BT modules, and many 4G/LTE modems to connect to an external RP-SMA antenna, improving signal range and reliability in final deployments or testing setups.

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

RP-SMA (Reverse Polarity SMA) has the gender of the inner conductor reversed compared to standard SMA. In an RP-SMA female connector, the center pin has a socket, while the standard SMA female has a center pin. This design is often used on consumer WiFi equipment to prevent connection with professional-grade antennas, ensuring regulatory compliance.

How do I properly install this cable on my IoT module?

First, ensure your module is powered off. Gently press the IPEX 1 connector onto the module's antenna pad until you hear/feel a faint click, indicating it is securely seated. Route the cable away from noise sources like digital lines or power supplies. Finally, screw the RP-SMA female end onto your external antenna's male RP-SMA connector, hand-tightening it to ensure a solid connection without over-torquing.
