Latest Patents
Christopher J Nunn holds 1 patent for his invention titled "Method and apparatus for controlling amplifier power." This patent describes a method and apparatus designed to control the power output of a transmitter RF amplifier. The invention includes a control circuit connected to the RF amplifier, which derives a control signal from a shaper circuit. This control signal, along with a feedback signal representing the flow of DC current through one of the amplifier's stages, is used to generate an error signal. The error signal is then applied to a common amplifier base bias line, allowing the amplification envelope of the transistors to follow the error signal, thus producing a pulsed output signal with an envelope shape that corresponds to the control signal.
