Mini PCI U.FL to RP-SMA pigtail for wireless modules

This 15 cm coaxial cable connects a device-side U.FL or IPX connector to an external RP-SMA female antenna. It is built for WiFi, WLAN, GPS, Bluetooth or Zigbee modules that use the 1.13 mm micro coaxial interface. The 50 Ohm impedance matches common wireless transceivers.

Signal integrity in a compact cable

The 1.13 mm outer conductor diameter and 50 Ohm characteristic impedance preserve signal quality across the short 15 cm run. No active components or shielding beyond the coaxial construction are specified, so thermal load and audible noise are negligible in normal operation. Power draw is limited to the passive transmission path.

Direct antenna attachment without adapters

The RP-SMA female end accepts standard SMA male antennas used on routers, GPS navigation systems or embedded boards. No additional software, drivers or mounting hardware are bundled; the cable itself is the complete accessory. Buyers who need a different connector gender, a longer run or an MHF-compatible plug will require a separate solution.

Questions about this item

How do I install the U.FL end onto the board without damaging the 2.5 mm high connector?

Align the tiny U.FL plug straight over the board receptacle and press down vertically with a fingertip until it clicks; angling the plug bends the 2.5 mm high shell and breaks the 1.13 mm outer conductor.

Will the 1.13 mm coaxial cable need periodic replacement?

The 1.13 mm cable is passive and has no wear items; replace it only if the jacket is kinked, the shielding is exposed, or the RP‑SMA threads are stripped.

What is the first limit reached during continuous RF transmission?

The 50 Ohm impedance match holds until the 1.13 mm centre conductor overheats, so sustained high‑power TX will hit thermal limits before signal loss appears.
