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
amplifers with extended low frequency performance
possible through the use of a high valued external
feedback blocking capacitor; extremely well matched
(–20 dB return loss) amplifers; and negative gain slope
amplifers for fattening MMIC cascades.
The MSA-series is fabricated using Avago’s 10 GHz
fT, 25 GHz fMAX, 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 fexibility.
