Friday, February 13th, 2009
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.
Designed in accordance with MIL-C-39012 specifications, SMA lineup has one of the most extensive variety of applications including Semi-Flexible/Flexible cable, Receptacle, PCB, and Reverse Polarity option.
