摘要：The present invention provides the efficient (for example) hard-limiting orswitch-mode power amplifier that control for highly efficient power. Between gapmaximum frequency needed for modulation and working frequency switch-mode DC-DCconverter, reduce by switch-mode converter and active linear adjuster. Linear regulatorcontrols the operating voltage of power amplifier, has enough bandwidth, to reproducerequired amplitude modulation waveform. Linear regulator refuses the variation on itsinput voltage, or even changes output voltage in response to applied control signalsimultaneously. Amplitude modulation is the power amplifier by changing operatingvoltage. Efficiently by allowing switching DC-DC converter to change its output voltage,low and relative constant level is adhered to the voltage drop shown on linear regulator.
