Cascadable Silicon Bipolar
MMIC␣ Amplifier
Technical Data
MSA-0285
Features
• Cascadable 50 Ω Gain Block
• 3 dB Bandwidth:
DC to 2.6 GHz
• 12.0 dB Typical Gain at
1.0␣ GHz
• Unconditionally Stable
(k>1)
• Low Cost Plastic Package
Description
The MSA-0285 is a high performance silicon bipolar Monolithic
Microwave Integrated Circuit
(MMIC) housed in a low cost
plastic 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.
