Preliminary
SUF-5000
0.1-3.7 GHz, Cascadable pHEMT
MMIC Amplifier
Product Description
Sirenza Microdevices’ SUF-5000 is a monolithically matched broadband
high IP3 gain block covering 0.1 - 3.7 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 0.86 mm2 die. It is well-suited for RF, LO, and IF driver
applications.
