The SMA connector (SubMiniature version A) is a type of coaxial RF connector developed in the 1960s. It is a threaded, weatherproof connector used in a variety of applications, including RF transmission, wireless communication, and satellite communication. It is one of the most popular RF connectors due to its small size, high performance, and reliability. The SMA connector consists of a center pin surrounded by a threaded coupling nut that ensures a secure connection.
It is a popular choice for many applications due to its robust design, excellent electrical performance, and wide availability.
The SMA connector is a two-piece connector consisting of a male and female connector.
The maximum frequency an SMA connector depends on a variety of factors, including the type of SMA connector, the cable used, and the environment in which the connector is used. General purpose SMA connectors are designed to support frequencies up to 18GHz, although this can vary depending on the specific connector and cable used. In addition there are a number of small select SMA Connectors for semi-rigid cables the can support a maximum frequency up to 34GHz
The maximum power an SMA connector can support depends on several factors, including the size of the connector, the type of cable used, and the environment in which the connector is used. Most SMA connectors can support 75 watts of power up to 10GHz . However, this power rating can be increased if the connector is used in a controlled environment, such as a laboratory or a factory. The size of the SMA connector also affects the maximum power it can support.
