Abstract
A power amplifying module includes an input end for inputting power, an output end for outputting amplified power, and an amplifier cascade. Each amplifier comprises at least a heterojunction bipolar transistor (HBT) connected with each other in a parallel manner. The closer the amplifier to the input end is, the smaller the number of HBTs the amplifier has.
