Patents by Inventor Michael Rauh

Michael Rauh has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus and method for processing of amplifier linearization signals
    Patent number: 7856105
    Abstract: A feed-forward amplifier includes a main amplifier having input signals and amplified output signals and an error amplifier for amplifying distortion signals to be added to the amplified output signals of the main amplifier to produce an amplifier output. A pilot tone modulation and recovery circuit modulates a pilot tone to be coupled to the input signals of the main amplifier and recovers the pilot tone from the amplifier output. The pilot tone modulation and recovery circuit includes a digital filter and a signal source. The signal source is used to both modulate the pilot tone and control the digital filter for recovering the pilot tone.
