TRI-BAND GSM/DCS/PCS FRONT-ENDS

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.
