SMA-male to U.FL Cables:  3 inches up to 10 feet

Antenna Cable / Adapter: SMA male to U.FL

  • Cable length refers to the length between the connectors (not including the connectors)
  • One end has a U.FL connector (female, right-angle), and the other has a SMA male connector.
  • Data Alliance's high-quality soldered terminations of SMA and U.FL connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

Coaxial cable type options for our U.FL cables:

  • Our 1.13mm mini-coaxial cable (Impedance: 50 Ohms) is a standout option. This cable is incredibly thin and flexible, and it has a black jacket. Its unique thinness (diameter is 1.13 mm) makes it perfect for connecting a U.FL connector to a jack on a mini PCI card or board in tight spaces. It's so thin that it's typically needed in tight spaces inside enclosures, ensuring the U.FL connector will snap down on the jack without popping off.

  • RG174 coax is thicker and has a lower signal loss (attenuation) than 1.13mm while flexible and easily bendable. RG174 is also better quality than 1.13mm and has a black jacket. The higher quality of this cable translates into lower loss and better performance. This cable is rated for outdoor use and is also suitable for indoor use. Note that the LMR-100 coax is too thick in diameter to use with U.FL connectors.

  • 1.32mm coax is double-shielded and thin (1.32mm diameter).
  • 1.37mm coax is another low-loss option.

  • Special Orders: Please see this page about options for the thickness of the coax. Note that we can make special orders with 1.13mm, RG174, 1.32mm, and 1.37mm coax if you want a lower-loss, thicker cable for the shorter versions of this cable. Contact us to make a particular order.

Compatibility with wireless standards and applications:

Our UFL to SMA "pigtail" cables offer exceptional compatibility with various wireless applications. With a frequency band range from 0GHz to 18GHz, low broadband VSWR, and 50 Ohm impedance matching, they are ideal for all WiFi standards, including 2.4GHz and 8GHz applications like Wi-Fi HaLow 802.11AH, 802.11AX, 802.11AC, 802.11N, 802.11G, 802.11B, and 802.11A,. They also support cellular wireless LTE / 4G, GSM / 3G, and WiMax for both data and voice applications. Additionally, our cables are perfect for IoT wireless, automation, and Machine to Machine (M2M) applications such as Bluetooth, ZigBee, WiFi HaLow, RFID, LoRa, LTE-m, and NB-IoT, WiFi 6, WiFi 6E. Moreover, they are compatible with all Helium miners used in Europe, including Bobcat miners, Sensecap miners, and other Helium LongFi miners, as are all of our antenna cables and adapters with SMA-male connectors.

U.FL Connector Characteristics

Overview

U.FL connectors, also known as Ultra Miniature Coax Connectors (UMCC), are widely used in IoT (Internet of Things) and M2M (Machine-to-Machine) applications. These micro-coaxial connectors are engineered for high-frequency signal transmission and are ideal for compact wireless modules.

Gender and Form Factor

  • U.FL Male Connector
    The male U.FL connector is typically found as the jack on devices such as:
    • Bluetooth modules
    • ZigBee radios (e.g., XBee)
    • Printed Circuit Boards (PCBs)
    • Internal mini-PCI wireless cards

Despite being technically male due to its center pin, it functions as the jack (receptacle), which is a reversal of conventional RF connector gender terminology.

  • U.FL Female Connector
    The female U.FL has a socket and is usually mounted on cables. It mates with the male jack on the device.

The right-angle U.FL female is by far the most common form found on U.FL cables — accounting for approximately 95% of cable applications.

Gender Identification Note

U.FL connector gendering is counterintuitive compared to standard RF conventions:

  • The U.FL jack on a board (often thought of as female) is actually male.
  • The cable connector that mates with the jack is female.

This distinction is critical for proper selection and mating in system design.

Tool-Assisted Handling

Due to their miniature size, proper connection and disconnection of U.FL connectors can be challenging and risk damaging sensitive components.

To ensure safety and ease:

  • Use a U.FL insertion/removal tool.
  • This tool prevents damage to:
    • U.FL cables
    • Connectors
    • On-board jacks

It simplifies installation and reduces the risk of connector or PCB failure during repeated use.

Construction and Performance

  • U.FL connectors are precision-machined and gold-plated brass for:
    • High reliability
    • Low signal loss
    • Consistent high-frequency performance

The U.FL female cable connector mates with the HiRose U.FL-LP-66 jack, offering secure, compact connectivity for embedded wireless modules.
