摘要： 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.

摘要： An evaluation method for linearity evaluations neither performing calculations of error vectors at multiple sampling points nor using a demodulator corresponding to a desired modulation scheme. Measuring devices (164 and 165) measure the input signal and the output signal of an evaluation object (1), to which a predetermined evaluation signal has been inputted. An evaluation unit (166) uses the input signal and the output signal of the evaluation object (1), to determine at least one of an amplitude distortion or a phase distortion of the output signal. An integration unit (169) uses the distortions to perform the integrations weighted by the probability density function of the power-to-average ratio of a predetermined modulated signal. A linearity index calculation unit (170) calculates a linearity index from the results of processing by the integration unit (169).
