Preliminary
SUF-4000
Product Description
Sirenza Microdevices’ SUF-4000 is a monolithically matched broadband
high IP3 gain block covering 0.15-10 GHz. 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 0.88 x 0.80 mm
2
die. It is well-suited for RF, LO, and IF driver
applications.
