CHA3689-99F
Description
The CHA3689-99F is a three-stage self biased wide band monolithic low noise
Vd1
Vd2 amplifier. RFin
It is designed for a wide range of applications, from military to mercial munication systems.
The circuit is manufactured with a p HEMT process, 0.25µm gate length, via holes through the substrate, air bridges and
B electron beam gate lithography.
It is available in chip form.
