SMA Female to IPEX4 RF Cable RG0.81 15cm

Description

This SMA Female to IPEX4 RF cable is a critical interconnect for integrating external antennas with modern compact wireless modules. It solves the common design challenge where device PCBs utilize tiny, pick-and-place IPEX4 (also known as u.FL) connectors for RF output, while most external antennas feature standard SMA interfaces. The cable uses RG0.81 coaxial construction, providing a balanced compromise between flexibility and signal loss for short-run applications.

With a frequency range covering DC to 6GHz, it is engineered to maintain impedance matching for 5G NR, 4G LTE, Wi-Fi 6, LoRa, and GNSS signals. The SMA female end is designed for chassis or panel mounting, offering a robust mechanical interface, while the IPEX4 plug ensures a reliable click-lock connection to module RF pads. This adapter is essential for prototype development, field testing, and final system integration where optimal antenna placement is required.
