APPARATUS FOR ELIMINATING HARMONIC COMPONENTS IN HIGH-EFFICIENCY LINEAR POWER AMPLIFIER SYSTEM USING DELAY ELEMENTS

摘要

A circuit for eliminating harmonic components in a linear power amplifier system using pulse modulation includes a divider for splitting an input signal into N signals, N being a natural number greater than 1; N time delay units for delaying the respective N signals by each of predetermined values; N linear power amplifiers using the pulse modulation for amplifying the delayed N signals; and a band pass filter for filtering off the harmonic components while the amplified delayed N signals are passing therethrough.
