    摘要: A stacked power amplifier is provided in which an input signal is independently coupled to each of a series of amplifying devices in the stack. A transformer is used at the input circuit of each device to create an RF swing across each amplifying device which is substantially equal. This results in an equal distribution of RF and DC voltage among the devices in the stack.
