Description

This SMA Female to IPEX1 RF pigtail cable is an essential RF interconnect for developers and integrators working with modern wireless modules. It bridges the gap between the compact, board-mounted IPEX1 (u.FL) connectors found on space-constrained cellular, GNSS, and Wi-Fi modules and the standard SMA female interfaces used by most external antennas. The cable utilizes RG1.13 coaxial construction, offering a balance of flexibility and signal integrity for frequencies from DC up to 6GHz.

The 13mm threaded SMA female connector is designed for secure panel mounting, providing a stable mechanical and electrical connection to an SMA male antenna. This setup is critical for maintaining impedance matching (typically 50 ohms) and minimizing VSWR, which directly impacts RF performance and range. By using this adapter, you can easily evaluate different antenna gains and positions or integrate a device into a final enclosure without permanent modification to the RF module itself.

Key Features

  • Interface Conversion: Adapts from a standard panel-mount SMA female connector to a miniature IPEX1 (u.FL) male connector.
  • Broad Frequency Support: Suitable for applications from DC up to 6000MHz, covering 2G/3G/4G/5G, GNSS, Wi-Fi, Bluetooth, and LoRa bands.
  • Low-Loss Cable: Uses RG1.13 coaxial cable, which provides good signal integrity and flexibility for short-run connections inside enclosures.
  • Secure Mechanical Connection: The SMA connector features a 13mm threaded interface for reliable panel mounting and strain relief.
  • Prototyping & Integration Essential: Solves the common problem of connecting external antennas to modules that only have tiny, surface-mount IPEX footprints.

Applications

  • Connecting external SMA antennas to compact 4G LTE (e.g., SIM7600, SIM800) or 5G cellular modules with IPEX footprints.
  • Adding a GNSS/GPS active antenna with an SMA connector to a tracking device using a u.FL GNSS module.
  • Extending the antenna port for Wi-Fi/Bluetooth SoC development boards (ESP32, Raspberry Pi CM4) to an enclosure panel.
  • Interfacing high-gain LoRa antennas with SMA connectors to LoRaWAN node modules (RAK3172, RN2483) that have IPEX1 pads.
  • General RF prototyping and testing where a temporary or configurable antenna connection is required.

Frequently Asked Questions

Is this cable compatible with my ESP32 module's external antenna pad?

Yes, if your ESP32 development board or module has a small, square IPEX1 (also called u.FL or MHF) connector soldered onto its antenna pad, this cable will connect it to a standard SMA male antenna. Ensure your board supports external antenna switching via a GPIO pin or jumper. The cable's frequency range covers both 2.4GHz Wi-Fi and Bluetooth bands used by the ESP32.

What is the difference between SMA and RP-SMA, and which one do I have?

SMA and RP-SMA (Reverse Polarity SMA) are mechanically incompatible. A standard SMA male has a pin in the center and internal threads, while an RP-SMA male has a center hole and external threads. This cable has a standard SMA female connector (center hole, internal threads). Check your antenna's connector: if it has a center pin, it's SMA male and will fit. If it has a center hole, it's RP-SMA male and will NOT fit this cable.

Can I use this pigtail for a 5G cellular module like the SIM8200?

Yes, this cable is suitable for 5G modules operating below 6GHz (Sub-6 GHz bands). The RG1.13 cable and connectors support frequencies up to 6000MHz. Connect the IPEX1 end to the main antenna port on your SIM8200 or similar 5G module and the SMA female end to your external 5G antenna. For optimal performance, keep the cable run as short as possible and avoid sharp bends to minimize signal loss.

How do I securely mount the SMA connector to my device's enclosure?

The connector has a 13mm threaded section. Drill a hole with the correct diameter for the SMA connector's body in your enclosure panel. Insert the connector from the inside, then screw the provided hexagonal nut (if included) or a panel-mount SMA jack from the outside to secure it. This provides strain relief and grounds the connector shield. Ensure no tension is placed on the delicate IPEX1 connection at the other end.
