RF cable adaptor (pigtail) U.FL(f) to QMA(f)

Features:

The adaptor is designed for the frequency range of the U.FL 0-6 GHz / QMA 0-6 GHz connector. The reduction is designed for the 0-3 GHz frequency range and achieves very low VSWR values, less than 1.40:1 over the entire frequency range. Connecting and detaching the U.FL and SMA connectors is easy, guarantee of 30 cycles due to the small size and strength of the U.FL connector. The FME connector has a guarantee up to 100 cycles. The QMA connector includes an O-ring that enhances water and dust sealing properties.

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

Coaxial cable LP 088

Cable features:

The LP 088 coaxial cable is compatible with connectors that are applicable to a 1.37 mm cable diameter. Due to its features and size, it is widely used in applications that require high-frequency transmission using miniature coaxial connections. The characteristic impedance of the cable is 50 Ω. 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 / FAKRA / FME / MHF / MCX / MMC / N / QMA / SMA / SMA-RP / SMB / SMP / 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.
