- Abstract
- Provided is a power amplifier of a low-power consumption system that has linearity at a peak output power while increasing efficiency in a most frequently used range, and thereby enables a battery to last longer. The power amplifier includes an input impedance matcher for impedance-matching a signal input from the outside; a high-power amplifier and a low-power amplifier for amplifying the signal having passed through the input impedance matcher; an amplification controller controlling the high-power amplifier and low-power amplifier according to the power level of the input signal; an output impedance matcher for impedance-matching the signal amplified by the high-power amplifier and low-power amplifier; and a dynamic voltage supplier for supplying the low-power amplifier with a variable driving voltage. With the constitution set forth above, linearity at peak output power is maintained, and efficiency increases in the most frequently used range, thereby enabling the battery of a handheld to last longer.
