Description
The MSA-0870 is a high performance silicon bipolar Monolithic
Microwave Integrated Circuit
(MMIC) housed in a hermetic, high
reliability package. This MMIC is
designed for use as a general
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.

Notes:
1. Permanent damage may occur if any of these limits are exceeded.
2. TCASE = 25°C.
3. Derate at 6.7 mW/°C for TC > 88°C.
4. 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.
