DESCRIPTION
The STB7001 is a Silicon monolithic amplifier, that
offers low noise figure and three gain levels for
900-MHz applications. STB7001 is housed in a
small industry-standard MSOP8 surface mount
package, requiring very little board space (50% re-
duction vs SO8 Package). MSOP8 dimensions
are 3mmx5mm with a 1.1mm thickness. The de-
vice is ESD protected and requires minimum ex-
ternal components in the application circuit, for the
on-chip bias and gain control . Furthermore, tem-
perature and supply voltage compensation as-
sures high stability over a wide range of operating
conditions.
