Description

The MSA-0420 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 50Ω gain block.

Typical applications include narrow and broad band IF

and RF ampliers in industrial and military applications.

The MSA-series is fabricated using Avago’s 10 GHz

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 exibility.
