Microstrip Package
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.
The MSA-series is fabricated using
HP’s 10 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.
Available in cut lead version
(package 36) as MSA-0636.

4. Storage above +150°C may tarnish the leads of this package making it
difficult to solder into a circuit.
5. The small spot size of this technique results in a higher, though more
accurate determination of
θ
jc
than do alternate methods. See MEASURE-
MENTS section “Thermal Resistance” for more information.
