Description

This IPEX to RP-SMA female pigtail is a critical RF interconnect for developers integrating wireless modules into final products. The IPEX (or MHF) connector is commonly found on compact ESP32, nRF52, and cellular modules where space is at a premium, while the RP-SMA female interface is the standard for many external Wi-Fi, GPS, or 4G antennas. The 15cm RG178 coaxial cable provides a balanced solution, offering enough length for flexible placement while maintaining signal integrity with its low-loss dielectric.

The assembly ensures reliable impedance matching (typically 50 ohms) across common IoT frequency bands, minimizing VSWR and preserving RF link budget. Its slim 11mm jacket diameter and flexible construction allow for clean routing within enclosures, making it suitable for drone telemetry, portable trackers, smart home hubs, and industrial sensor nodes where a permanent external antenna connection is required.

Key Features

  • Provides a secure, impedance-matched bridge from internal module IPEX pads to external RP-SMA antenna ports.
  • Flexible RG178 coaxial construction enables easy installation in confined spaces without compromising cable integrity.
  • Maintains signal quality for high-frequency applications including 2.4GHz/5GHz Wi-Fi and 4G LTE bands.
  • Precision-machined connectors ensure consistent mating and reduce insertion loss for optimal RF performance.
  • Essential for product development, allowing antenna testing and optimization during the prototyping phase.

Applications

  • Connecting ESP32, Raspberry Pi, or cellular module development boards to external high-gain antennas.
  • Extending wireless range in compact IoT devices like Bluetooth trackers, LoRaWAN sensors, and Wi-Fi cameras.
  • Enabling antenna diversity setups in RF gateways and routers by linking multiple IPEX ports.
  • Facilitating field-replaceable antenna systems in industrial telemetry and automotive telematics units.

Frequently Asked Questions

What is the difference between IPEX and u.FL connectors?

IPEX and u.FL are often used interchangeably, but they are technically different series from the same manufacturer (I-PEX). Both are micro-miniature coaxial connectors with a similar latch mechanism. For practical purposes in IoT, they are compatible and refer to the same small, board-mounted RF connector used on ESP32, nRF, and cellular modules. This cable uses the IPEX (MHF) series interface.

Can I use this cable to connect a 4G LTE module to an external antenna?

Yes, this cable is suitable for 4G LTE applications. The RG178 coaxial cable supports frequencies up to 6 GHz, covering all standard LTE bands (700 MHz to 2.7 GHz). Ensure your cellular module (e.g., SIM7600, EC25) has an IPEX connector and your external antenna has an RP-SMA male plug. This setup can significantly improve signal strength and reliability in remote IoT deployments.

How do I properly install and route this pigtail cable inside an enclosure?

First, securely mate the IPEX connector to your module's pad, applying even vertical pressure until it clicks. Route the flexible RG178 cable away from power traces or noisy digital components to minimize interference. Use adhesive cable clips or tie-downs to prevent strain on the connector joint. Finally, attach the RP-SMA end to your antenna port, hand-tightening the connector without over-torquing to avoid damaging the threads.
