Description
The MSA-0235 is a high performance silicon bipolar Monolithic
Microwave Integrated Circuit
(MMIC) housed in a cost effective,
microstrip 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 industrial and military applications.
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 metallization 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.

Thermal Resistance[2,5]:
θjc = 145°C/W
Notes:
1. Permanent damage may occur if any of these limits are exceeded.
2. TCASE = 25°C.
3. Derate at 6.9 mW/°C for TC > 153°C.
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 θjc than do alternate methods. See MEASUREMENTS section “Thermal Resistance” for more information.
