Description
The MSA-0370 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
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 f
bipolar MMIC process which uses
nitride self-alignment, ion implantation, and gold metallization to
