,
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-0236.

Description
The MSA-0235 is a high perfor-
mance silicon bipolar Monolithic
Microwave Integrated Circuit
(MMIC) housed in a cost effective,
microstrip package. This MMIC is

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.
