The SMA connector is a type of coaxial connector commonly used in radio frequency (RF) applications. It features a threaded coupling mechanism, which provides a secure connection and helps maintain signal integrity. SMA connectors are often used in telecommunications, antennas, and test equipment due to their compact size and reliable performance. These connectors are designed to operate at frequencies up to 18 GHz, making them suitable for various applications, including Wi-Fi, cellular networks, and satellite communications. The SMA connector is available in both male and female versions, allowing for versatile connections in different setups.
