SMA connector's features and applications

Author: Date:5/15/2019 1:39:03 AM
 SMA connectors,are widely used half-precision ultra-small RF microwave connector, especially for RF connections in electronic systems with frequencies up to 18 GHz or higher.



SMA connectors come in a variety of styles, male, female, straight, right angle, spacer fittings, etc., to meet most requirements. Its ultra-small size also enables it to be used, even in relatively small electronic devices. It is commonly used to provide RF connections between boards, many of which include filters, attenuators, mixers and oscillators, using SMA connectors.


The connector has a threaded external connection interface that has a hexagonal shape that allows for tightening with a wrench. They can be tightened to the correct seal with a special torque wrench so that a good connection can be achieved without over-tightening. The required torque is typically 8 inch lbs.


Features and benefits of SMA connectors:

Light weight, compact structure, shockproof design

Low cost commercial grade (brass SMA), nickel plated or gold plated

Ends with all standard flexible coaxial cables, low loss (LMR) cables and industry standard semi-rigid and conformable cables
