What is SMA in RF?

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. The connector has a 50 Ω impedance.

Is K connector compatible with SMA?

Yes. SMA, 3.5mm, and 2.92mm (K) connectors all have similar mechanical characteristics which allows them to be mated to each other. Similarly, 2.4 mm and 1.85 mm connectors are also compatible with each other.

Is 3.5 mm the same as SMA?

SMA and 3.5mm are matable connectors. The SMA connector is an economical, lower performance interface. SMA type will have a foam bead, while 3.5mm uses an air interface. Due to cost, the 3.5mm connector is most often used in metrology applications, whereas the SMA connector is used for production.

What is SMA thread?

SMA and RP-SMA are standard threaded antenna connectors for high frequency applications from 1 GHz to approx. 16 Ghz. They are most commonly used in microwave systems, such as portable radio and mobile phone antennas, but also with WiFi antenna systems.

Is N connector same as SMA?

An additional advantage of type-N connectors is that they are meant to be hand-tightened, whereas SMA connectors should be tightened with a torque wrench to achieve the best performance. The main advantage of the SMA connector seems to be size, since it’s quite a bit smaller.

What is a RP SMA connector?

Reverse polarity SMA (RP-SMA) is a variation of the SMA connector specification which reverses the gender of the interface, as shown in Figures 1-4 below. Similarly, the RP-SMA(M) has threads on the inside like a conventional male, but has a center receptacle instead of the male pin in the middle.
