plastic package. This MMIC is
designed for use as a general
purpose 50
gain block. Typical
applications include narrow and
broad band IF and RF amplifiers
in commercial and industrial
applications.
The MSA-series is fabricated using

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.
