Cascadable Silicon Bipolar
MMIC␣ Amplifier
Technical Data
MSA-0185
Features
• Cascadable 50 Ω Gain Block
• 3 dB Bandwidth:
DC to 1.0 GHz
• High Gain:
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.
17.5 dB Typical at 0.5 GHz
• Unconditionally Stable
(k>1)
• Low Cost Plastic Package
The MSA-series is fabricated using
HP’s 10 GHz fT, 25␣ GHz f
silicon bipolar MMIC process
which uses nitride self-alignment,
ion implantation, and gold metalli-
Description
The MSA-0185 is a high performance silicon bipolar Monolithic
Microwave Integrated Circuit
(MMIC) housed in a low cost
plastic package. This MMIC is
zation to achieve excellent
performance, uniformity and
reliability. The use of an external
bias resistor for temperature and
current stability also allows bias
flexibility.
