RFMD’s SUF-4000 is a monolithically matched broadband high IP
3
gain
block covering 0.15GHz to 10GHz. This pHEMT FET-based amplifier uses
a patented self-bias Darlington topology featuring a gain and temperature
compensating active bias network that operates from a single 5V supply.
It offers efficient, cascadable performance in a compact
0.88mmx0.80mm die. It is well suited for RF, LO, and driver applications.
