An N to SMA adapter is a type of RF (radio frequency) connector adapter that allows for the interconnection of devices with N-type connectors to those with SMA connectors. N-type connectors are larger, durable, and typically used in high-frequency and high-power applications, while SMA connectors are smaller and commonly used for precision and high-frequency RF connections. The adapter facilitates seamless signal transfer between these differing connector types, enabling compatibility between a wider range of RF equipment.
