SMA connectors were developed in the 1960s, have a 50 ohm constant impedance and a bandwidth of up to 18GHz. Being intended for use with semi-rigid coax on RF paths inside equipment they are not ...

An SMA edge connector may be designed to present a characteristic impedance of 50Ω typically, but that is to the end of the connection pins. Once it’s soldered down, there is a discontinuity ...

Originally developed in the 1960s, SMA feedthroughs, also referred to as SubMiniature version A connectors, integrate a coaxial cable with a minimalistic screw-type interface. Their low electrical ...
