The SMA connector, also known as the SubMiniature version A connector, is a coaxial RF connector that is commonly used in telecommunications, military and aerospace applications. The SMA connector is designed to provide a secure connection with low signal loss, making it ideal for high-frequency applications that require low interference and low noise. The SMA connector has a male and a female version, with the male connector having a threaded outer conductor and a center pin that protrudes from the center of the connector, while the female connector has a threaded inner conductor and a center hole that accepts the center pin of the male connector.
