Description

This SMA Female to IPEX4 connector cable is a fundamental RF accessory for IoT hardware integration. It solves the common design challenge of interfacing standard, panel-mount SMA antenna connectors with the miniature, board-level IPEX4 (also known as u.FL) ports found on most compact wireless modules. The RG0.81 coaxial cable is engineered for minimal insertion loss across a broad spectrum from DC to 6GHz, covering critical bands for 5G, 4G LTE, GNSS, Wi-Fi, Bluetooth, and LoRaWAN communications.

With a 20cm length and flexible build, it allows for strategic antenna placement within a device enclosure, improving signal reception and transmission range. The precise 11mm IPEX4 connector ensures a snap-fit, reliable connection that withstands vibration, making it suitable for both development and deployment in mobile or industrial environments. Always verify your module’s connector type (IPEX4) and your antenna’s gender (SMA Male typically mates with this SMA Female pigtail) for compatibility.

Key Features

  • Interface adapter for connecting SMA panel-mount antennas to IPEX4 (u.FL) module connectors.
  • Broadband frequency coverage from 0 to 6000MHz for multi-protocol wireless applications.
  • RG0.81 coaxial cable type offers a balance of flexibility and RF performance.
  • SMA Female connector with outer thread and inner hole for standard antenna mating.
  • IPEX4 connector is the common standard for ESP32, cellular (SIM7xxx, SIM8xxx), and GPS modules.
  • 20cm cable length provides adequate reach for optimal antenna positioning inside a case.
  • Essential for final product assembly where an internal antenna port must connect to an external antenna.

Applications

  • Connecting external SMA antennas to 4G LTE (SIM7600, SIM7070) or 5G cellular modules with IPEX ports.
  • Adding an external GPS/GNSS antenna to compact tracking devices or development boards.
  • Extending the Wi-Fi/BLE range of ESP32, ESP8266, or other wireless SoC modules.
  • Integrating high-gain LoRa antennas with RN2483, RN2903, or SX1276/SX1262-based nodes.
  • General RF prototyping and testing where a u.FL to SMA transition is required.

Frequently Asked Questions

What modules is this IPEX4 to SMA cable compatible with?

This cable is compatible with any wireless module featuring a standard IPEX4 (also called u.FL or MHF) male connector. This includes common IoT boards like ESP32/ESP8266 development kits, 4G LTE modules (SIM7600 series, SIM7070), GPS/GNSS receivers (NEO-6M, NEO-8M), and LoRa transceivers (SX1276, SX1262). Always verify your specific module's datasheet for the connector type, as some may use IPEX1 or other variants.

How do I correctly connect this cable to my board and antenna?

First, gently snap the IPEX4 connector onto the matching port on your wireless module, ensuring it clicks into place. Then, screw the SMA Female connector onto the threaded male pin of your external antenna. Hand-tighten only; do not over-torque. Ensure the antenna's frequency band matches your application (e.g., 868MHz for LoRa, 2.4GHz for Wi-Fi). Route the cable away from noise sources like power supplies or digital lines to minimize interference.

What is the significance of the RG0.81 cable specification?

RG0.81 refers to the coaxial cable's diameter and construction, which determines its impedance (typically 50 ohms for RF), flexibility, and signal loss per meter. This specific type offers a good balance for prototyping: it's thin and flexible for routing inside enclosures while maintaining acceptable attenuation up to 6GHz. For longer runs or higher-frequency applications, a lower-loss cable like RG316 might be preferred, but RG0.81 is ideal for most compact IoT device internal connections.
