• Low Cost Plastic Package
in a low cost plastic package. This
MMIC is designed for use as a
general purpose 50
Ω
gain block.
Typical applications include
narrow and broad band IF and RF
amplifiers in commercial systems.
The MSA-series is fabricated using
HP’s 10 GHz f
T
, 25 GHz f
MAX
,
silicon bipolar MMIC process
which uses nitride self-alignment,
ion implantation, and gold metalli-
zation to achieve excellent
performance, uniformity and
reliability. The use of an external
bias resistor for temperature and
current stability also allows bias
flexibility.
