SMA Female to U.FL Interface Cable

SMA Female to U.FL Interface Cable

The SMA Female to U.FL Interface Cable is a premium, low-loss radio frequency (RF) coaxial pigtail designed to bridge micro-miniature surface-mount wireless modules with standard high-gain external antennas. Featuring a chassis-mountable SMA Female bulkhead connector on one end and a snap-on U.FL (IPEX) connector on the other, this cable is essential for RF prototyping. It ensures low signal attenuation and stable impedance matching. Consequently, your cellular, GPS, or Wi-Fi hardware can maintain a clear, high-performance network link without experiencing dropped packets or signal degradation.

Key Features

• Precision bulkhead design allows the SMA Female connector to bolt directly through external project enclosures.

• Ultra-compact U.FL terminal snaps securely onto high-frequency PCB micro-pads with a satisfying click.

• Heavy-duty internal shielding minimizes radio frequency interference (RFI) across the entire transmission path.

• Highly flexible coaxial strand enables tight routing paths inside dense drone or IoT enclosures.

• Heavy gold plating on internal pins optimizes electrical conductivity and resists oxidation.

• Pre-installed lock washer and hex nut hardware ensure a vibration-proof panel installation.

• Low insertion-loss profile preserves weak satellite signals for sensitive GPS and GNSS modules.

• Standardized 50-ohm characteristic impedance perfectly matches industrial wireless hardware specifications.

Applications

Wireless hardware developers frequently use the SMA Female to U.FL Interface Cable to attach high-gain cellular antennas to 4G LTE and 5G IoT telemetry boards. Additionally, it provides the precise link necessary to hook up external patch antennas to multi-constellation GPS navigation modules. Drone builders install this pigtail inside carbon fiber airframes to route delicate receiver signals out to external video and control antennas. It is also an ideal solution for upgrading desktop computer Wi-Fi cards, configuring custom LoRa gateway enclosures, and assembling compact software-defined radio (SDR) test benches.

Performance and Specifications

When implementing high-frequency communication setups, physical stability and signal integrity are critical factors. This interface cable utilizes high-grade mini-coaxial shielding to isolate delicate data lines from surrounding electromagnetic noise. The threaded SMA Female end mates flawlessly with standard male antenna pins, providing an airtight, wobble-free mechanical connection. Meanwhile, the micro-U.FL end saves vital circuit board space on compact modules. Measuring an optimized length, this pigtail minimizes signal dampening while giving you enough slack to mount your connectors neatly on any structural panel.
