U.FL to SMA-female Cables: 1FT to 41 inches

Antenna Cable: SMA female to U.FL: Length options:

  • Choose among length options 12 inches up to 26 inches on this page, above.
  • Other length options: 1-inch, 2", 3", 4-inch, 5-inch, 6-inch, 7-inch, 8-inch, 9-inch and 10-inches.
  • The length refers to the cable length between the connectors (not including the connectors).
  • 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.

One end has a U.FL connector, and the other has a SMA female (bulkhead) connector.

Coaxial cable type options for our U.FL cables:

  • RG174 coax is thicker and has a lower signal loss (attenuation) than 1.13mm while also being flexible/easily bendable. RG174 is better quality than 1.13mm and has a black jacket. The higher quality of this cable translates into lower loss/better performance. This cable is rated for outdoor use and is also suitable for indoor use. Note that LMR-1the 00 coax is too thick in diameter to use with U.FL connectors.

  • 1.13mm mini-coaxial cable (Impedance: 50 Ohms ): This is a very thin, 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 the U.FL connector will snap down on the jack without popping off.
  • 1.32mm coax is double-shielded and thin (1.32mm diameter).
  • 1.37mm coax is another low-loss option.
  • Special Orders: Please see this note about options for the thickness of the coax. 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. Don't hesitate to contact us to make a particular order.

  • Please see this note about options for the thickness of the coax. For better flexibility, we can make special orders with 1.13mm cable.

SMA-female connectors: Characteristics


SMA Female connector differences



U.FL Connectors Characteristics

  • U.FL female has a socket. U.FL female right-angle type is the most common.
  • The type of U.FL connector found on U.FL cables is the U.FL female right-angle connector, which is found on 95% of U.FL cables.
  • 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' 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, such as Bluetooth beacons.

Gender Determination: Micro-connectors such as U.FL have a gender that is counter to typical RF terminology for gender, in that "jack" is more typically synonymous with "female:" A U.FL jack on a board (PCB) is the male U.FL, and the connector that mates with the jack is the female.

  • Properly connecting and disconnecting U.FL connectors from the jack can be difficult without damaging the connector or jack. We offer a U.FL insertion tool to enable you to 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.

RoHS 3 and REACH compliant: All of our antenna cables and RF adapters are compliant with RoHS 3 and REACH standards of content limits of lead and other toxic materials.

Compatibility with wireless protocols and applications:

Our U.FL cables' range of frequency band compatibility (from 0 to 18GHz) and 50 Ohms impedance matching make them suitable and compliant for all the above applications.
