SMA coax connector is a precision coaxial connector for microwave applications. SMA RF connectors have a thread interface and 50 ohm dependence just like N, FME, SMA, SMC other RF connectors and so on. It can be crimped with RF coaxial cable from 0.81mm to 1.48mm.
SMA connector male straight crimp for 0.81mm (PN#C01AA31081004), 1.48mm coax cable (PN#C01AA31148004) is same as SMA connector male straight crimp for RG178, 1.13mm coax cable. Please link to get details and drawings.
