SMA-female (right-angle) To U.FL Cable: 2-inch 3" 4" 6" 8" 14" 32-inch Adapter

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 end has a SMA female right-angle connector with a bulkhead for mounting.

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

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 U.FL connector to a jack on a miniPCI card or board, often the tight space requires the use of 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 of enclosures, so that the U.FL connector will snap down on the jack without popping off.

RG174 coax is thicker and has 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-100 coax is too thick in diameter to use with U.FL connectors.

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

Special Orders: Please see this note about options for thickness of the coax, and 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 special order.

SMA female connector includes a bulkhead nut and washer:

• 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 Bard (PCB).
• Weatherproofing: Seal the hole where the female connector is mounted, by placing an O-ring between the wall of the enclosure and the bulkhead nut & washer on the female connector.
• The length of our standard SMA-female connector (threaded part) is 3/8 inches (9.525mm). We have a longer option: 14.5mm, which we can use for special-order cable requests.
• All of our cables with SMA and RP-SMA female connectors have bulkhead mount hardware.

SMA female diameter:

• Hex nut accommodates a screw/bolt with 5/16" nominal outer diameter.
• In other words, the inside diameter of the hex bolt is 5/16".

SMA is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz: This antenna cable is compliant for all types of wireless antennas, including wireless / WiFi networks, Bluetooth, ZigBee, Cellular voice & 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.

SMA Connector Composition: Our SMA connectors are precision machined and gold-plated for low loss.

• Center Contact: Beryllium Copper, Gold Plated
• Connector Body: Brass, Gold Plated
• Crimp Ferrule: Copper, Nickel Plated
• Insulators: PTFE

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 have made them popular over the years in many applications. The UFL to SMA series pigtail is impedance matched to 50 ohm cables.

Compatibility with wireless protocols and applications:

• All WiFi standards: 2.4GHz and 5GHz applications: 802.11AC, 802.11N, 802.11G, 802.11B, 802.11A
• Cellular Wireless LTE / 4G, GSM / 3G WiMAX: Data and voice applications
• IoT wireless, automation & M2M: Bluetooth, ZigBee, RFID, LoRa, LTE-m, NB-IoT

Our U.FL cables' range of frequency band compatibility (from 0 to 18GHz) and 50 Ohms impedance matching, makes 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" that is embedded directly on to 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 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.

• Connecting and disconnecting U.FL connectors from the jack can be difficult to do properly without damaging the U.FL connector or jack. We offer a U.FL insertion tool to enable you to connect/insert and remove/disconnect easily, without causing any damage to 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: The shell and contact of Female U.FL connectors are made of phosphor bronze but are silver, and gold-plated respectively. Female U.FL connectors are the ones used in the termination of antenna cable.
• 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 free of 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.
