Adapter for antenna Cable: U.FL-female to SMA female

  • One end has a U.FL female connector and the other end has a SMA female straight connector.
  • See also our UFL to SMA "pigtail" cables.

Compatibility with wireless standards & applications

This antenna cable adapter's 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 male has a pin and is the connector that is the "jack" on a 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.
  • U.FL connectors are widely used in M2M and IoT (Internet of Things) wireless applications.
  • 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.

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 antenna to a U.FL jack/connector on PCBs: U.FL female mates with a female HiRose/U.FL jack, also known as U.FL-LP-66 jack/connector.
  • U.FL connector is precision machined and gold-plated brass for low signal loss.

SMA Gender Determination: Key Point

  • SMA gender is counter-intuitive: Please observe picture & note it is correct.  
  • The gender is referring to the pins inside-not the threads. SMA male has threads on inside.

SMA male and female diameter:

  • SMA female outside diameter is 5/16" (7.9375mm): Accommodates a hex nut (bulkhead nut) with 5/16" nominal outer diameter
  • SMA male inside diameter is 5/16" (7.9375mm) (the inside diameter where the threads are).

SMA-Connector Materials Composition

  • Connector Body: Gold Plated Brass
  • Center Contact: Beryllium Copper, Gold Plated
  • Crimp Ferrule: Copper, Nickel Plated
  • Insulators: PTFE
  • Precision machined for low loss in ISO 9001 facilities

Other SMA Characteristics and Key Points

  • SMA female connector is also called "jack" and SMA-male is also called "plug."
  • We offer an SMA wrench to assist in installing antennas, cables and adapters with SMA or RP-SMA connector(s).
  • SMA-female connector fits items that have an SMA-male connector.
  • 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.
  • SMA connectors are not compatible with the common, commercially available Type F coaxial connector. Type F connectors look similar but are of slightly different size and will not pair with RP-SMA connectors without an adapter.

RoHS 3 and REACH compliant: All of our RF adapters and antenna cables are compliant with RoHS 3 and REACH restrictions for content of lead and other heavy metals and toxins.
