ABSTRACT:
A power amplifier based on EER technology or ET technology extracts an amplitude-modulated component from a modulated signal as an input signal which includes the amplitude-modulated component and a phase-modulated component, and decomposes the amplitude-modulated component into two control signals whose product is proportional to the amplitude-modulated component. One of the control signals is amplified by a highly efficient amplifier, and thereafter is used to amplitude-modulate an output from an RF amplifier. The other control signal is converted by a pulse modulator into a rectangular-wave signal, which is then mixed with the phase-modulated component or the modulated signal and input to the RF amplifier.
