Silicon Bipolar RFIC Amplifiers
Technical Data
MSA-31XX Series
Description
The MSA-31XX series are high
performance silicon bipolar RFIC
amplifiers designed to be
cascadable in 50
systems. The
stability factor of K > 1 contrib-
utes to easy cascading in
numerous narrow and broadband
IF and RF commercial and
industrial applications.
The MODAMP MSA series is
fabricated using a 10 GHz f
T
,
25 GHz F
MAX
, silicon bipolar RFIC
process which utilizes nitride self-
alignment, ion implantation, and
gold metallization to achieve
excellent uniformity,
performance, and reliability. The
use of an external bias resistor for
temperature and current stability
also allows bias flexibility.
Package options include, the
industry standard plastic surface
mount SOT-143 package, the
100 mil surface mountable
hermetic ceramic package, the
85 mil plastic microstripline
package, and the 85 mil surface
mountable plastic microstripline
package.
