SMA的意思

05-08

请问，SMA是什么意思?哪几个词的简称呢还是另有玄机?

是一种射频接头标准吧，和N 型和7/16 应该是一种。

SMA接头

SMA (SubMiniature version A) connectors are coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw type coupling mechanism. The connector has a 50 Ω impedance. It offers excellent electrical performance from DC to 18 GHz.

3 楼回答是正确的，很标准。把它的形状、阻抗、截止频率都说明了。
当然，也可简单理解：SMA=Small A type
