The SMA connector produced by our company is threaded connection, which has quick and reliable connection, anti-vibration and stable performance. It can be used interchangeably with the same international specifications.

SMA series coaxial connector

product description

The SMA series is a wide range of small threaded coaxial connectors with high frequency bandwidth, excellent performance, high reliability and long life. It is suitable for connecting RF cables or microstrip lines in the RF loop of microwave equipment and digital communication systems.

Series of SMA products one application extensive small-scale coaxial person who join that whorl join, it has a reliable characteristic with long life-span that the width, performance are excellent, high frequently. Suitable for the microwave equipment and body of the digital communication System and join the body in the cable or the micro-strip line frequently in the loop frequently
