Latest Patents

Fraise's latest patents include a "Microwave mixer with recovery of the sum frequency." This invention features a microelectronic circuit composed of one or more active electronic elements with nonlinear characteristics, all carried on a substrate. The elements are supplied by waveguide lines placed on the substrate, and the circuit is enclosed within a closed casing. It connects to terminals that mix an incident wave with a mixing wave, resulting in a mixed wave output. The internal cavity of the casing is tuned to a 'sum' frequency, which is the sum of the frequencies of the incident and mixing waves.

Another significant patent is the "Microwave filter incorporating dielectric resonators." This filter includes a waveguide and an electromagnetically coupled dielectric resonator. A slot, which constitutes the waveguide, is cut into a metal plate that forms part of the filter. The resonator is separated from the metal plate by a dielectric support, enhancing the filter's performance.
