| dc.description.abstract | This paper presents the `Envelope Following’
Technique for raising power efficiency in mobile
communication systems. The designed power supply system
includes a 2.13 GHz power amplifier in which the input battery
voltage of 5 V is boosted to a variable voltage output of 28 V
depending on the incoming radiofrequency envelope. This
variable voltage is obtained using an envelope detector and a
dc-dc boost converter. For an output power level of 45 dBm, the
power efficiency increases from 72.4% to 85.4% extending
battery life over 1.2 times. | es_ES |
