MSA-9970
Cascadable Silicon Bipolar MMIC Amplifier
Data Sheet
Description
Features
The MSA-9970 is a high performance silicon bipolar
Monolithic Microwave Integrated Circuit (MMIC) housed
in a hermetic high reliability package. This MMIC is
designed with high open loop gain and is intended to
be used with external resistive and reactive feedback
elements to create a variety of special purpose gain
blocks.
Applications include very broadband, minimum ripple
amplifiers with extended low frequency performance
possible through the use of a high valued external
feedback blocking capacitor; extremely well matched
(–20 dB return loss) amplifiers; and negative gain slope
amplifiers for flattening MMIC cascades.
• Open Loop Feedback Amplifier
• Performance Flexibility with User Selected External
Feedback for:
Broadband Minimum Ripple Amplifiers
Low Return Loss Amplifiers
Negative Gain Slope Amplifiers
• Usable Gain to 6.0 GHz
• 16.0 dB Typical Open Loop Gain at 1.0 GHz
• 14.5 dBm Typical P_{1 dB} at 1.0 GHz
• Hermetic Gold-ceramic Microstrip Package
The MSA-series is fabricated using Avago’s 10 GHz
f_T, 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.
