Power amplification apparatus using switching structure in a wireless communication system and method for controlling the same |
摘要 |
A power amplification apparatus includes a carrier amplifier and a peaking amplifier. In the apparatus, a detection and comparison controller detects an envelope signal from an input signal, compares a value of the envelope signal with a threshold, and generates a control signal corresponding to a threshold power. At least one switch performs a switching operation for turning on/off the peaking amplifier according to the control signal.
