FAQ:

Q: What kind of coaxial cable connector is SMA?

A: SMA connector. Jump to navigation Jump to search. Coaxial cable connector with semi-precision minimal connector interface developed in the 1960s. SMA (SubMiniature version A) connectors are semi-precision coaxial RF connectors developed in the 1960s as a minimal connector interface for coaxial cable with a screw-type coupling mechanism.

Q: Is the RP-SMA connector a male or female connector?

A: A male RP-SMA connector is the opposite in both respects – male connector body (inside threads) with a female inner sleeve contact Reverse-polarity SMA (RP-SMA or RSMA) is a variation of the SMA connector specification that reverses the gender of the interface, as shown in Figures 1 and 2.

Q: What kind of dielectric is used for SMA connectors?

A: The SMA connector uses a polytetrafluoroethylene (PTFE) dielectric that contacts along the mating plane. Variability in the construction and the mating of the connectors limits the repeatability of the connector impedance.

Q: Can a Type F connector be mated with a SMA connector?

A: Type F cannot be mated with SMA connectors without the use of an adapter. The SMA name is also used for a superficially similar optical fiber connector . The interface dimensions for SMA connectors are listed in MIL-STD-348.
