SMA Female to IPEX4 Connector Cable 30cm RG0.81

Description

This SMA Female to IPEX4 connector cable is a critical RF accessory for wireless system integration. The RG0.81 miniature coaxial cable provides a balanced compromise between flexibility and low attenuation, maintaining signal integrity for frequencies up to several GHz. The 30cm length offers practical routing flexibility inside device enclosures, allowing optimal antenna positioning away from potential sources of interference.

The SMA female connector is the industry-standard threaded interface for external antennas, while the IPEX4 (often referred to as U.FL) is the dominant ultra-miniature connector for on-board wireless modules from ESP32, nRF52, Quectel, and Semtech families. This pigtail ensures a 50-ohm impedance-matched path, minimizing VSWR and preserving RF power transfer between the module and the antenna for maximum range and data reliability.
