Latest Patents

One of Yu Cao's latest patents is titled "Double-disc structure for self-biased circulators monolithically integrated on semiconductors." This invention presents a self-biased circulator that is notably smaller and lighter than traditional models, which rely on bulk permanent magnets. The miniaturization of self-biased circulators allows for their integration into monolithic microwave integrated circuits (MMICs) on a single chip. This innovation facilitates full-duplex communication in radio frequency (RF) bands exceeding the Ka band, while minimizing losses through connectors. The new double-disc structure utilizes two self-biased discs, significantly improving insertion loss, isolation, bandwidth, and power handling capability.

Another notable patent is for a "High electron mobility transistor." This device features a gallium nitride layer with multiple two-dimensional electron gas channels, enhancing its performance. The design includes a gate contact with a gate bus that has several gate feet extending into the gallium nitride layer. Each gate foot is trapezoid-shaped, optimizing the transistor's functionality. The source and drain contacts are strategically placed to maximize efficiency.
