Well, let's talk to you:SMA RFIntroduction to coaxial connector


SMA RF coaxial connector was designed as an OSM connector by Bendix in the late 1950s. It was one of the most commonly used RF / microwave connectors at that time. Initially, SMA connectors were designed for 0.141 ″ semi-rigid coaxial cables and precision connectors for microwave applications in the military industry, filled with PTFE media.

Under the conditions at that time, due to the small volume and high frequency (the frequency range of semi-hard cable is DC ~ 18GHz; that of flexible cable is DC ~ 12.4ghz), SMA connector was quickly popularized. Even later developed millimeter wave connectors.


The full name of SMA is smallatype. It is a typical microwave high frequency connector. Its highest frequency is 18GHz. It is a widely used coaxial connector with small threaded connection. SMA connector is suitable for connecting RF cable or microstrip line in RF loop of microwave equipment and digital communication system.


SMA series RF coaxial connector is a small RF coaxial connector with threaded connection. Its characteristic impedance is 50 Ω and the frequency range is 0 ~ 18GHz. It has the advantages of wide frequency band, excellent performance, high reliability and long service life.
