U.FL to RP SMA

Antenna Cables with U.FL connector & RP-SMA connector

Most of Data Alliance's U.FL to RP-SMA cables are made with 1.13mm coax (especially for shorter lengths).  We use RG174 coax (2.54mm diameter) for longer lengths.  Both coax types have 50 Ohm impedance, and both coaxes have a black jacket. 1.13mm coaxial cable is very thin and very flexible cable, which makes it very suitable for the tight spaces where the U.FL connectors need to connect to the jack on the miniPCI board or card.   RG174 has lower attenuation (signal loss).    

RP-SMA to U.FL cables are compatible with antennas of WiFi frequency bands between 0 and 18GHz and all 802.11 WiFi standards, as well as BlueTooth, ZigBee, and LoRa.

RP-SMA connectors:  A threaded,medium-sized, threaded and round screw type connector made for use from 0GHz (DC) up to 11GHz. Since it has very low broadband Voltage Standing Wave Ratio (VSWR), it has become one of the most common connectors that has found usage in all manner of applications.

U.FL connectors:  Ultra Miniature Coax Connector (UMCC) is another name for the U.FL connector. The U.FL connector series are typically attached to the U.FL connector/jack on internal-PCI wireless cards and Printed Circuit Boards (PCB). Given their miniature size, they have found use in the IoT (Internet of Things) applications including BlueTooth beacons.

The female U.FL connector mates with the U.FL-LP-66 jack that is popular with Bluetooth beacons, mini-PCI wireless cards, and ZigBee radios such as XBee.
