U.FL to MMCX Cables:  3 inches to 36 inches

Antenna Cable / Adapter: U.FL to MMCX right-angle: The length refers to the cable size between the connectors (not including the connectors).

Compatible wireless applications: This antenna cable's range of frequency band compatibility (from 0 to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm gear makes them compatible and compliant for all the following applications:

The size of U.FL and MMCX connectors makes them an excellent fit in the Internet of Things (IoT) applications since they take up very little space in the cramped cases of small devices, such as Bluetooth beacons.

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

Coaxial Cable Types for U.FL to MMCX cables

  • The coaxial cable type is RG174. RG174 is 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.
  • Option: 1.13mm mini-coaxial cable (50 Ohm impedance): 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. The 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.
  • Special Orders: Please see this note about options for the thickness of the coax. 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. 1.32mm coax is double-shielded while also very thin (1.32mm diameter). Contact us to make a special order.

U.FL cable connectors gender and composition of materials

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 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.

RoHS 3 and REACH compliant: Our antenna cables and RF adapters are free of heavy metals and compliant with RoHS 3 and REACH.
