DESCRIPTION
The STB7002 is a Silicon monolithic amplifier, that
offers low noise figure and three gain levels for
1.8GHz applications. STB7002 is housed in a
small industry-standard MSOP8-EP surface
mount package, requiring very little board space
(50% reduction vs SO8 Package). MSOP8-EP
dimensions are 3mmx5mm with a 1.1mm
thickness. STB7002 is ESD protected and
requires minimum external components in the
application circuit, for the on-chip bias and gain
control. Furthermore, temperature and supply
voltage compensation ensures high stability over
a wide range of operating conditions.
