U.FL to SMA-female Cable

Coaxial cable type options for our U.FL cables:

  • 1.13mm mini-coaxial cable (impedance: 50 Ohms): This is a very thin and flexible cable with a black jacket. When connecting a UFL connector to a jack on a mini PCI card or board, the tight space often requires a 1.13mm cable because it is very thin and flexible (diameter is 1.13mm). This very thin cable is typically needed in tight spaces inside enclosures so that the U.FL connector will snap down on the jack without popping off.

  • RG-174 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 very thin (1.32mm diameter).

  • 1.37mm coax is another low-loss option.

  • Special Orders: We can make special orders with 1.13mm, RG174, or 1.32mm coax if you want a lower-loss, thicker cable for the shorter versions of this cable. To request a particular order, contact us with your requirements.

SMA Female Connector Characteristics:

Multiple versions we offer of SMA Female Connetor types

Coax types for U.FL to SMA cables: 1.13mm, 1.32mm, 1.37mm, RG174.  Specifications compared.

U.FL Connectors Characteristics

  • U.FL female has a socket. U.FL female right-angle type is the most common U.FL connector type found on U.FL cables: 95% of U.FL cables have a U.FL female right-angle connector.
  • U.FL male has a pin and is the connector: Male U.FL is the gender that is the "jack" embedded directly onto a circuit board on devices such as Bluetooth boards and ZigBee radios such as XBee, Printed Circuit Boards (PCBs), and internal mini-PCI wireless cards (even though the gender is male, it is the jack U.FL connector. Hence, the male connectors/jacks are very rigid.
  • U.FL connectors' small size has made them an excellent fit in Machine-To-Machine (M2M) and IOT (Internet of Things) wireless applications. They occupy very little space in the cramped cases of small devices like Bluetooth beacons.
  • Gender Determination: U.FL connectors have a unique gender determination that may differ from typical RF terminology. Here's a simplified explanation: A U.FL jack on a board (PCB) is the male U.FL, and the connector that mates with the jack is the female.
  • U.FL Insertion Tool: Properly connecting and disconnecting U.FL connectors from the jack can be difficult without damaging the connector or jack. Our U.FL insertion tool is designed to make this process easy and safe, ensuring you can connect/insert and remove/disconnect easily without damaging the cable, connector, or jack.
  • The U.FL connector, also known as Ultra Miniature Coax Connectors (UMCC), enables attaching an external antenna to a U.FL jack/connector on Printed Circuit Boards (PCBs): The U.FL female mates with a female HiRose/U.FL jack, also known as the U.FL-LP-66 jack/connector.

U.FL Connectors' Material composition

  • Male has a silver-plated phosphor bronze made the shell and a gold-plated brass made contact.
  • Female: Female U.FL connectors' shell and contact are made of phosphor bronze but are silver and gold-plated, respectively. They are used to terminate antenna cables.
  • U.FL connectors are precision machined. The gold-plating enables low signal loss.

Compatibility with wireless standards and applications:

Our UFL to SMA "pigtail" cables' range of frequency band compatibility (from DC 0GHz to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm antennas and cables make them suitable and compliant for all the above applications.

RoHS 3 and REACH compliant: We understand the importance of safety and environmental responsibility in your applications. That's why all of our antenna cables and RF adapters, including the U.FL to SMA-female Cable, comply with the content of heavy metals and other toxic materials that are restricted by RoHS 3 and REACH, giving you peace of mind about the safety and environmental friendliness of our products.

    Too much time spent scrounging around on eBay for replacement cables from dodgy eBay sellers. So glad I found Data Alliance - I get *exactly* what I need for mu projects, and no questions about quality. Thanks!
