The SUF-5033 is a monolithically matched broadband high IP3 gain block
covering 0.1GHz to 4.0GHz. This pHEMT FET-based amplifier uses a pat-
ented self-bias Darlington topology featuring a gain and temperature com-
pensating active bias network that operates from a single 5V supply. It
offers efficient, cascadable performance in a compact 3mmx3mm
Ceramic QFN package. It is well-suited for RF, LO, and IF driver applica-
tions.
