Description

This SMA Female to IPEX4 RF cable is a critical interconnect for integrating external antennas with modern compact wireless modules. It solves the common design challenge where device PCBs utilize tiny, pick-and-place IPEX4 (also known as u.FL) connectors for RF output, while most external antennas feature standard SMA interfaces. The cable uses RG0.81 coaxial construction, providing a balanced compromise between flexibility and signal loss for short-run applications.

With a frequency range covering DC to 6GHz, it is engineered to maintain impedance matching for 5G NR, 4G LTE, Wi-Fi 6, LoRa, and GNSS signals. The SMA female end is designed for chassis or panel mounting, offering a robust mechanical interface, while the IPEX4 plug ensures a reliable click-lock connection to module RF pads. This adapter is essential for prototype development, field testing, and final system integration where optimal antenna placement is required.

Key Features

  • Converts panel-mount SMA female connector to IPEX4 (u.FL/MHF) male plug for module interconnection.
  • Supports a wide RF spectrum from 0 to 6000MHz, covering all major cellular, IoT, and navigation bands.
  • Constructed with RG0.81 coaxial cable (0.81mm diameter) for minimal signal attenuation over short distances.
  • SMA connector features an outer-thread, inner-hole (female) design for secure antenna or bulkhead mounting.
  • IPEX4 connector length is 11mm, providing a secure latch connection to compatible module sockets.
  • Essential for adapting external high-gain or directional antennas to compact IoT dev boards and cellular modems.

Applications

  • Connecting external SMA antennas to 4G LTE (e.g., SIM7600, SIM7000) or 5G cellular modules with u.FL outputs.
  • Extending Wi-Fi/BT range on ESP32, ESP8266, or Raspberry Pi Compute Modules with IPEX connectors.
  • Integrating high-gain LoRa/LoRaWAN antennas (SMA) to compact RF modules like the RAK3172 or SX1262.
  • Providing a GNSS/GPS antenna connection for precision timing and location modules in tracking devices.
  • Prototyping and testing RF performance in IoT devices, routers, drones, and wireless sensor networks.

Frequently Asked Questions

Is this cable compatible with my ESP32-S3 module that has a u.FL connector?

Yes, the IPEX4 connector on this cable is mechanically and electrically identical to the common u.FL (also called MHF) socket found on ESP32-S3, ESP8266, and many other Wi-Fi/BLE modules. Ensure your module's RF output pad uses the standard u.FL footprint for a secure click-lock connection. The SMA female end can then be attached to any standard SMA male antenna to extend wireless range.

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

This cable has a standard SMA female connector, characterized by an outer thread and an inner hole (female pin). RP-SMA reverses this, having an outer thread with an inner pin. They are not mechanically compatible. Most external antennas and cellular/LoRa gateways use standard SMA male. Always verify your antenna's connector type before purchase to ensure a proper mate and avoid damage.

Can I use this RG0.81 cable for a 5G NR application at 3.5GHz?

Yes, the cable is rated for frequencies up to 6GHz, covering all sub-6GHz 5G NR bands including 3.5GHz (n78). The RG0.81 coaxial construction provides acceptable signal integrity for short 15cm runs typical in device integration. For optimal performance in critical 5G deployments, ensure the cable is routed away from noise sources and connectors are firmly tightened to maintain 50-ohm impedance.
