U.FL-male to RP-SMA-male (Right Angle or Straight): 1-inch, 2-in, 3-in Cable Adapter

U.FL-male to RP-SMA-male (Right Angle or Straight)

Antenna Cable / Adapter: RP-SMA male to U.FL-male

• One end has a U.FL connector male, and the other has an RP-SMA male connector.
• The cable length is between the connectors (not including the connectors).
• The cable type is 1.13, except the 2-inch version has an option for LMR-100 (double-shielded low-loss).
• Note that RP-SMA-male has a socket, not a pin, inside. This is what SMA Reverse Polarity means.

On this page, you may purchase RP-SMA-male right-angle and RP-SMA male straight versions.

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 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. Note that the LMR-100 coax is too thick in diameter to use with U.FL connectors.
• 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 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.

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 compact size and versatility of U.FL connectors make them perfect for Machine-To-Machine (M2M) and IoT (Internet of Things) wireless applications. They efficiently utilize space in small devices, such as Bluetooth beacons, instilling confidence in their adaptability.
• Gender Determination: In the context of connectors, 'jack' refers to the part of the connector embedded directly on a circuit board. 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 U.FL.

Connecting and disconnecting U.FL connectors from the jack is a breeze with our U.FL insertion tool. This tool empowers you to connect/insert and remove/disconnect easily, without causing any damage to the cable, connector, or jack. The U.FL connector, or 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: 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 meticulously precision machined, ensuring their high quality and reliability. The gold-plating further enhances their performance, enabling low signal loss and instilling a sense of assurance in their functionality.

RP-SMA Connectors Characteristics

• • RP-SMA is a round screw-type connector with medium-sized, threaded coupling connectors rated for frequencies from the lowest (DC) up to 18GHz.
  • SMA connector material composition
  •  
  • The RP-SMA-male connector fits items with an RP-SMA (female) jack/connector: RP-SMA = Reverse-Polarity SMA.

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

  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.
