Description
The MSA-0485 is a high perfor-
mance silicon bipolar Monolithic
Microwave Integrated Circuit
(MMIC) housed 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 and industrial
applications.
85 Plastic Package
The MSA-series is fabricated using
HP’s 10 GHz fT, 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.
