Patent JP-2001189630-A (JP)
Title: Method for generating amplified signal
Inventor: MA ZHENGXIANG
IPC: H03F3/68
Filed: 2000-11-17
Abstract: PROBLEM TO BE SOLVED: To provide an efficient power amplifier architecture for linearly amplifying a signal having the possibility of high peak power. SOLUTION: An amplified signal is generated by decomposing a signal 16 into two parts 18 and 22, amplifying these parts and coupling the amplified parts. The decomposition is performed so as to have characteristics capable of facilitating the efficient amplification in the part to be obtained. For example, the signal to be amplified is decomposed while using at least one threshold 20. The part 18 of the signal to be amplified is formed from the part of a signal within the threshold. Since the part 18 forms a signal having low PAR, the part 18 of the signal can be efficiently amplified rather than the original signal. The part 22 of the signal is formed from the part of the original signal, which exceeds the threshold. Since the part 22 is almost zero, the part 22 can be efficiently amplified by a C-class amplifier, which does not consume energy when an input signal is zero.
