U.FL to SMA Cables & Adapters for Antennas

U.FL connector to SMA connector antenna cables are coaxial cables characterized by their threaded, medium-sized coupling connectors made for use from DC to 11GHz. They also have consistently low broadband Voltage Standing Wave Ratio (VSWR), which has made them one of the most popular cables for all manner of applications. The impedance of the U.FL to SMA series pigtail is 50 Ohms.

The Coaxial Cable:   Data Alliance uses 1.13 coax for shorter U.FL cables and typically RG174 for longer U.FL cables.  The 1.13mm diameter and very flexible 1.13 is sometimes a necessity - if the space is very tight inside small cases that house PCBs (Printed Circuit Boards), and mini-PCI wireless cards.  Data Alliance will customize the coax option, as needed.


The U.FL Connector (sometimes referred to as the Ultra Miniature Connector (UMCC)) is at a right-angle in all of Data Alliance's U.FL cables, and connects the antenna cable to the U.FL connector/jack on internal mini-PCI wireless cards, and Printed Circuit boards (PCB).  U.FL Connectors are often used in embedded wireless systems for Internet of Things (IoT) devices.

The U.FL female connector is compatible with the antenna jacks of a variety of PCB boards and mini-PCI cards. It connects to the U.FL LP 66 cable connector common in mini-PCI wireless cards including XBee on ZigBee radios, Ubiquiti, MikroTik, and Intel PRO WiFi cards. The U.FL jack on the card makes it possible to connect a female U.FL connector to the external antenna of your mini PCI wireless card. 

The SMA Connector is a round screw type of connectors that are characterized by threaded, medium-sized coupling connectors that are suitable for frequencies of 0 GHz up to 18GHz. The antenna cable is compatible with all types of antennas including cellular voice and data, ZigBee, Bluetooth, WiFi and wireless networks, and WiMAX: 802.11n, 5GHz and 2.4GHz, and 900 MHz applications across a frequency range of between 0 to 18GHz.

Most U.FL connectors and SMA connectors are gold plated for minimal signal loss.
