Title: David Benoit Didier Duperray: Innovator in Transmission Technology
Introduction
David Benoit Didier Duperray is a notable inventor based in Redwood City, CA (US). He has made significant contributions to the field of transmission technology, holding 2 patents that showcase his innovative approach to solving complex engineering challenges.
Latest Patents
One of his latest patents is titled "Multiple transmission apparatus with reduced coupling." This invention relates to a transmission apparatus that features at least two transmission branches for transmitting respective signals at substantially the same frequencies. The design includes a first oscillator circuit for generating a first signal at a specific frequency and a second oscillator circuit for generating a second signal at a different frequency. To facilitate the transmission of signals at similar frequencies, the apparatus incorporates a frequency divider or multiplier, allowing for reduced mutual coupling between the branches.
Another significant patent is "Transmitter with transmitter chain phase adjustment on the basis of pre-stored phase information." This invention involves a transmitter chain that includes a quadrature modulator, a variable gain amplifier, an up-converter, and a variable gain power amplifier. The overall phase of the transmitter chain is adjusted based on pre-stored phase information, which reflects phase changes due to simultaneous gain adjustments in the variable gain amplifier and the variable gain power amplifier.
