Extend Talk Time in 3G Handsets
Fairchild Semiconductor’s RF power DC-DC converter, the FAN5902, helps to extend talk-time by up to 40 minutes in 3G handsets by adapting the voltage supply level of the 3G RF power amplifier according to the RF power sent through the antennae, enabling higher power efficiency for a wide range of antenna power levels.
