U.FL-R-SMT RF Coaxial Connector IPEX-1

The U.FL-R-SMT RF Coaxial Connector is a small surface-mount connector commonly used for radio frequency (RF) applications, especially in wireless communication devices. Here's a breakdown:

U.FL (IPEX): This is a type of ultra-miniature RF connector developed by Hirose Electric Group. It is also known as IPEX in many contexts. It is used in devices where space is limited and is often employed for connecting antennas in Wi-Fi, GPS, and cellular modules.
SMT (Surface Mount Technology): This indicates that the connector is designed to be mounted on the surface of a printed circuit board (PCB), rather than using through-hole technology.
RF (Radio Frequency): The connector is intended for RF signals, which are typically high-frequency signals used in wireless communication systems.
Coaxial: This refers to the type of cable or connector that has an inner conductor surrounded by an insulating layer, which is then enclosed by an outer conductor. Coaxial cables are used to carry RF signals with minimal interference.

The U.FL connector is often used in applications such as Wi-Fi modules, Bluetooth devices, cellular antennas, and GPS systems where space is a constraint. It is known for being easy to connect and disconnect, but frequent handling can wear it out, so it’s typically not meant for repeated use.
