Product Description

Technical Parameters.

In order to give you the best price, please kindly specify your requirements as clearly as possible.
OEM and ODM is welcome, we have professional and experienced engineer team for you.

Introduction:
JML-A-QMA coaxial fixed attenuators absorb RF& microwave power and suitable applications include radio base stations and other radio equipment, especially where high density connector population is required. 

QMA connector, the quick-insertion edition of SMA, has an approximately identical inner structure with the latter. The QMA interface features a snap-lock mechanism that makes it fast and easy to mate and de-mate, the QMA connector can rotate freely in range of 360 degree after linked, which makes the process of assembly more convenient.
