发明名称 High efficiency microwave amplifier
摘要 Disclosed is an apparatus and method for operating a microwave amplifier (140) with improved efficiency and reduced harmonic emissions. The disclosed amplifier includes a variable rail voltage supply (120) and a variable input drive stage (130). A controller (110) continually monitors the amplifier output and adjusts the rail voltage and input drive signal to achieve high efficiency and low harmonic emissions. The amplifier may include a dynamic bias controller configured to operate the gain elements outside the linear region. Efficiencies of over 70% may be achieved by the disclosed amplifier.
