Claim:
1. A power amplifier, comprising: a first power amplifying path to receive a first input signal within a first frequency range, wherein the first input signal corresponds to one of a plurality of first sub-frequency bands of the first frequency range; a first matching module comprising a first input end and a first output end, wherein the first input end is coupled to the first power amplifying path, and the first matching module further comprises: a second power amplifying path to receive a second input signal within a second frequency range, wherein the second input signal corresponds to one of a plurality of second sub-frequency bands of the second frequency range, and wherein the frequencies of the second frequency range are higher than those of the first frequency range; and a second matching module comprising a second input end and a second output end, wherein the second input end is coupled to the second power amplifying path, and the second matching module further comprises:
