Latest Patents
One of Yinggang Li's latest patents is the "Waveguide interface and non-galvanic waveguide transition for microcircuits." This invention relates to a metalized waveguide interface designed to provide a galvanically isolated waveguide connection for a propagating signal. It allows for a connection between a standardized waveguide and a metalized chip-level waveguide that is not compatible with the standardized waveguide. The configuration includes multiple open-ended quarter wavelength waveguides and a trench that creates a short-circuit half wavelength waveguide when the metalized chip-level waveguide is mounted on the support surface.
Another significant patent is the "Frequency multiplier with balun function." This invention focuses on generating a differential output signal from a single-ended input signal. The frequency multiplier includes a single-ended input to receive the input signal and differential outputs to provide the differential output signals. It comprises two signal branches, each containing filters and nonlinear components configured to generate differential output signals with a frequency that is a multiple of the input signal frequency.
