Types of SMA connectors

NameInsulatorMaximum bandwidth, GHzIs comply withDescription
Precision 1mmAir, gap 1mm110only with 1mmMuch smaller than other
Precision 1,85mmAir, gap 1,85mm702,4mmThe outer thread size of the 1.85 and 2.4 connectors is bigger than SMA, 3.5, and 2.92. This makes the area of the outer conductor mating surface look very large compared to the relatively small air dielectric.
Precision 2,4mmAir, gap 2,4mm501,85mmmanufactured at Keysight
Precision 2,92mm (also named “K”)Air, gap 2,92mm403,5mm and SMA(regular) 
Precision 3,5mmAir, gap 3,5mmmm342,92mm and SMA(regular)

Programs for electronics

In engineer’s work or hobbyst we must use  computers and tools. We need dedicated  programs to simulate, design or do equations for projects. In this article I will describe some electronics programs. This article is good for beginners. Continue reading Programs for electronics
