LP3939
Power Amplifier Driver for Dual Band CDMA Handsets
General Description
Designed
specifically
for
Qualcomm’s
MSM3xxx
and
MSM5xxx series, the LP3939 is an integrated device that
provides interface to the baseband processor to power-
switch two independent power amplifiers in dual band appli-
cations. By integrating the discrete components necessary
to achieve the same functions, the LP3939 drastically re-
duces board space and component cost.
