RF cable adaptor (pigtail cabel) from U.FL(f) to U.FL(f), length 3.5 cm


U.FL (f) miniature RF cable adaptor with LP-040 series cable, 3.5 cm cable length and 0.81 mm diameter. Connecting and disconnecting U.FL connectors is easy. Due to the very small size and strength of the connector, we are guaranteeing 30 cycles.

Cable adaptors (pigtails) then serve as an extension for connecting for example 2G/3G/LTE/Wi-Fi/GPS antennas to various PCBs, modules, Mini PCI cards etc.

Connector A + B


U.FL connectors are used in applications where there is very little space for connecting / interconnecting RF components.

Coaxial cable LP 040

Cable features:

The LP 040 coaxial cable is compatible with connectors that are applicable to a 0.81 mm cable diameter. Due to its features and size, it is widely used in applications that require high-frequency transmission using miniature coaxial connections. It is suitable for applications involving RF communication equipment, as well as electronic measuring instruments. It is most often used for creating cable adaptors with connectors such as U.FL/SMA/FME/MCX/TNC and others. The resulting cable adaptors are most often used to connect external antennas to eg cellular modules or IoT/NB-IoT/WiFi/GNSS and other RF devices.

We are a Czech producer of custom cable adaptors. Use our simple configurator to specify your requirements. You can also contact our sales department for advice on choosing the right connector and cable.
