Latest Patents

One of Soulard's latest patents is a compact power amplifier for microwave circuits. This innovative amplifier comprises a plurality of identical transistors, with grid buses of adjacent transistors interconnected by a grid matching circuit. The drain arrays of these transistors are also interconnected by a drain matching circuit. This design ensures that input levels to each transistor are identical in amplitude and phase, allowing for optimal performance. The amplifier's input is located on the grid bus of a transistor at one end of the series connection, while the output is on the drain array of a transistor at the other end. This configuration enables the assembly of an arbitrary number of transistors in a power amplifier, resulting in a smaller footprint.

Another notable patent is for a high-gain amplifier designed for the microwave frequency band. This invention proposes interconnecting amplification circuits and covering the housing with a lid. Inside the housing, waveguides are provided, which prevent the propagation of unwanted modes at working frequencies. This design significantly improves radio isolation between the output and input, allowing for amplification levels of up to 90 dB, surpassing the previous limit of 45 dB per housing.
