Five-Pack U.FL to RP-SMA Pigtails

This five-pack supplies 15 cm coaxial pigtails that convert a U.FL or IPX receptacle on a mini-PCIe or M.2 wireless module to an RP-SMA female bulkhead. Each cable presents a 50 Ohm impedance and uses 1.13 mm outer-conductor micro-coax suited to Wi-Fi, Bluetooth, GPS, Zigbee and similar RF links.

Length and Connector Constraints

The fixed 15 cm length limits routing to internal chassis runs or very short external hops; longer antenna placement will require an additional RP-SMA extension cable. The U.FL end mates with the standard 2.5 mm height micro connector, so modules using the smaller MHF footprint will not connect without an adapter.

Passive RF Link Thermals

As a purely passive coaxial assembly the pigtails generate no heat and add no audible noise to the system. Insertion loss is determined by the 1.13 mm cable geometry and 50 Ohm characteristic impedance at the frequencies used by the attached wireless module.

Questions about this item

Will the U.FL connector fit the 2.5 mm header on my existing mini-PCIe wireless card?

The U.FL connector is designed to the standard 2.5 mm height and 3 mm width, matching typical mini-PCIe and M.2 wireless modules.

How can I confirm the pigtail is passing signal correctly after installation?

Connect the RP-SMA female end to an antenna, attach the U.FL end to the radio module, then check received signal strength or link quality in the device software.

Does the pack include antennas or only the five 15 cm U.FL to RP-SMA female cables?

The package contains five 15 cm coaxial pigtails with U.FL male to RP-SMA female connectors; antennas are not included and must be sourced separately.
