FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The STB7003 is a tri-band LNA designed for GSM/DCS/
PCS applications. The GC pin sets the LNA gain levels.
The innovative architecture implemented allows to
reach very low current consumption. LNA1 works at
0.9-1.0 GHz and LNA2 over the 1.8-2GHz frequency
range.
