- SMA Product Series
FEATURE & APPLICATIONS
SMA series are popular 50 ohms RF connectors, using a threaded interface, providing reliable and excellent electrical performance in high frequencies. They are widely used in aero and aero space, military weapons, wireless network, and microwave devices or data communication. They also attach semi-flex or semi-rigid cables working up to 18GHz.
