U.FL To RP-SMA-female Cable: 16-inch, 18-in, 20-in, 22-in, 2ft, 30", 3FT, 40"

U.FL To RP-SMA-female Cable

Antenna Cable / Adapter: RP-SMA female to U.FL length options:

• 16-inch to 40-inch options: Choose the length above on this page
• 12 inch & 14-inch versions
• 8-inch & 10-inch options
• 4-inch & 6-inch options

One end has a U.FL connector, and the other has an RP-SMA female connector.

Coaxial cable types for our U.FL cables: We offer a variety of stock length options (on this page) made with different coaxial cable types. Some are made with 1.13mm, which is thin and flexible, while others are RG174, which is thicker and has lower signal loss. Each type has its own advantages, so choose the one that best suits your requirements.

• 1.13mm mini-coaxial cable (Impedance: 50 Ohms): This is a very thin and flexible cable with a black jacket. When connecting a U.FL 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.
• RG174 coax is thicker and has a lower signal loss (attenuation) than 1.13mm while also being 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. It's important to note that the LMR-100 coax is too thick in diameter to use with U.FL connectors. Using a cable with the wrong diameter can lead to poor signal quality or even damage your equipment.1.32mm coax is double-shielded and very 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 RG174, 1.13mm, 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.

RP-SMA female connector includes a bulkhead nut and washer:

• This can be used to mount the connector (and thus the cable) on the wall of a network enclosure (to weatherproof the cable connection) or on a case, panel, or Printed Circuit Board (PCB).
• Weatherproofing: Seal the hole where the female connector is mounted by placing an O-ring between the enclosure's wall and the bulkhead nut and washer on the female connector.
• Our standard RP-SMA-female connector (threaded part) length is 3/8 inches. We have a more extended option: 14.5mm, which is available. The longer 14.5mm option has an O-ring embedded in the flange to waterproof the port where the cable enters a network enclosure.

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 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 size of U.FL connectors has made them an excellent fit in Machine-To-Machine (M2M) 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.
• Connecting and disconnecting U.FL connectors from the jack can be difficult to do properly without damaging the 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.
• The 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): 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: 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 used in terminating antenna cables.
• U.FL connectors are precision machined. The gold-plating enables low signal loss.

Compatibility with wireless protocols and applications:

• All WiFi standards: 2.4GHz and 5GHz applications: Wi-Fi 6, WiFi 6E, 802.11AX, 802.11AC, 802.11N, 802.11G, 802.11B, 802.11A.
• Cellular Wireless LTE / 4G, GSM / 3G WiMAX: Data and voice applications.
• IoT wireless & M2M: Bluetooth, ZigBee, RFID, LoRa, LTE-m, NB-IoT.

Our UFL to RP-SMA "pigtail" 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.

ROHS 3 and REACH compliant: The entire product is ROHS 3 compliant and free of lead and other heavy metals.

Data Alliance's high-quality soldered terminations of U.FL and RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.
