MSA-2111
Cascadable Silicon Bipolar MMIC Amplifier
Data Sheet
Description
The MSA-2111 is a low cost silicon bipolar Monolithic Mi-
crowave Integrated Circuit (MMIC) housed in a surface
mount plastic SOT-143 package. This MMIC is designed
for use as a general purpose 50 Ω gain block. Typical ap-
plications include narrow and broad band IF and RF am-
plifiers in commercial and industrial applications.
The MSA-series is fabricated using Avago’s 10 GHz f
T
,
25 GHz f
MAX
, silicon bipolar MMIC process which uses ni-
tride self-alignment, ion implantation, and gold metalli-
zation to achieve excellent performance, uniformity and
reliability. The use of an external bias resistor for temper-
ature and current stability also allows bias flexibility.
