    Thin wire

    I've not been able to test the quality of the picture yet, but overall the product seems fine. Only thing I would change is use a little thicker gauge wire for the pigtail.

SMA-female (right-angle) To U.FL Cable

Antenna Cable / Adapter: U.FL To SMA female (right-angle). One end has a U.FL connector (mates with U.FL-LP-66), and the other has a SMA female right-angle connector with a bulkhead for mounting.

Cable length options: Choose 3-inch, 4-inch, 6-inch, and 8-inch options on this page.

Coaxial cable type options for our U.FL cables:

U.FL Coaxial cable type comparison

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 fragile 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.

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.

Special Orders: Please take a look at 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. Contact us to make a particular order.

SMA female connector includes a bulkhead nut and washer:

Multiple options of SMA Female connectors

  • You can use this to mount the connector (and thus the cable) on the wall of an enclosure (to weatherproof the cable connection), case, or Printed Circuit Board (PCB).
  • Weatherproofing: Seal the hole where the female connector is mounted by placing an O-ring between the enclosure wall and the bulkhead nut & washer on the female connector.
  • Our standard SMA-female connector (threaded part) is 3/8 inches (9.525mm) long. We have a more extended option, 14.5mm, which we can use for special-order cable requests.
  • All our cables with SMA and RP-SMA female connectors have bulkhead mount hardware.

SMA is a round screw-type connector with medium-sized, threaded coupling connectors rated for frequencies from the lowest (DC) up to 18GHz. This antenna cable is compliant with all types of wireless antennas, including wireless / WiFi networks, Bluetooth, ZigBee, Cellular voice and data, and WiMAX: 802.11N, AC, G, A, B. 900MHz, 2.4GHz, and 5GHz applications, as well as any other frequency between 0 and 18GHz.

UFL to SMA series coaxial pigtails have medium-sized, threaded coupling connectors designed for use from DC to 11 GHz. Their consistently low broadband VSWR has made them popular in many applications. The UFL to SMA series pigtail is impedance matched to 50 ohm cables.

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.

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.
  • The small size of U.FL connectors has made them an excellent fit in Machine-To-Machine and IoT (Internet of Things) wireless applications since they take up 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.
  • U.FL connector is also known as Ultra Miniature Coax Connectors (UMCC) and enables attaching an external antenna to a U.FL jack/connector on Printed Circuit Boards (PCBs):
  • U.FL female mates with a female Hirose/U.FL jack, also known as 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: Our antenna cables and RF adapters are free of heavy metals and compliant with RoHS 3 and REACH.

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.
