Challenge: Miniaturization and Connectivity
In modern IT hardware and network technology, devices are becoming increasingly compact, often leading to tiny and delicate antenna connectors on PCBs. These U.FL connectors are space-saving but susceptible to mechanical stress and require special adapters to connect external antennas with the more common SMA interfaces. A direct connection is often impractical or impossible, and inferior adapters can lead to signal loss and instability.
The Solution: The Coaxial Pigtail SMA Female to U.FL
Our Coaxial Pigtail P-UF-SF-20 provides the ideal bridge here. It converts the sensitive U.FL connector of your WLAN module, LTE modem, GPS receiver, or IoT device into a robust SMA female connector. With a length of 20 cm, this pigtail allows for flexible positioning of the external antenna without stressing the PCB. The high-quality manufacturing and the RG178 cable ensure reliable signal transmission and minimize attenuation losses, even at higher frequencies.
Technical Details that Convince
This pigtail is equipped with a U.FL male connector side that seamlessly connects to the corresponding jacks on your PCB. The SMA female connector at the other end is often designed as a bulkhead version, allowing for secure mounting through a housing or panel and providing additional protection against mechanical stress. The RG178 coaxial cable used is characterized by its small diameter of approx. 1.8 mm and its high flexibility, which significantly facilitates installation in confined spaces. It has an impedance of 50 Ohms, which corresponds to the standard for RF applications and ensures optimal signal transmission. The frequency coverage typically ranges from DC to 6 GHz for the U.FL connector and up to 18 GHz for the SMA connector, supporting a wide range of applications such as WLAN (2.4 GHz, 5 GHz), Bluetooth, LoRa, LTE, and GPS. The inner conductors of the RG178 cable are made of silver-plated stranded copper, which optimizes conductivity and prevents corrosion. The FEP jacket of the cable also offers high temperature resistance from -55°C to +200°C and is resistant to UV radiation, water, oil, and chemicals, ensuring a long lifespan.
Your Advantage: Stable Connections for Demanding Projects
With this pigtail, you invest in the stability and performance of your wireless applications. Whether you are realizing an IoT project, want to improve the WLAN range of your router, or need a reliable LTE connection for industrial applications – this adapter ensures a low-loss and secure connection for your external antennas. The easy installation and high material quality make it the first choice for professionals and ambitious home users.
