MSA-0686
Cascadable Silicon Bipolar MMIC Ampli er
Data Sheet
Description
The MSA-0686 is a high performance silicon bipolar
Monolithic Microwave Integrated Circuit (MMIC) housed
in a low cost, surface mount plastic package. This MMIC
is designed for use as a general purpose 50 gain block.
Typical applications include narrow and broad band IF and
RF ampli ers in commercial and industrial applications.
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 metal-
lization to achieve excellent performance, uniformity and
reliability. The use of an external bias resistor for tempera-
ture and current stability also allows bias  exibility.
