Introduction

Mahesh Kumar is a prominent inventor based in Hauppauge, NY (US). He holds a total of 7 patents that showcase his expertise in the field of microwave integrated circuits. His innovative contributions have significantly advanced technology in radio frequency applications.

Latest Patents

Among his latest patents, Mahesh Kumar has developed a hybrid microwave integrated circuit that features a radio frequency (RF) integrated circuit. This circuit includes a first layer of semiconductor material where a high electron mobility transfer (HEMT) device is formed. A semiconductor heat spreader substrate supports this first layer, while a pair of matching circuits are electrically connected to the HEMT device. These matching circuits are supported on a semiconductor substrate made of a different material than that of the first semiconductor heat spreader substrate. The thickness of the first layer and the first semiconductor heat spreader substrate is less than that of the semiconductor substrate supporting the matching circuits. Another notable patent is an integrated microwave transistor amplifier that includes an AlGaN/GaN active transistor arrangement on a thinned Si 1-mil heat spreader. This design features elongated, plated-through vias extending from the source portions of the transistor arrangement through the spreader to a thick gold supporting layer. A matching circuit is defined on a four-mil GaAs substrate, also supported by a thick gold layer. A stepped heat sink supports both the matching circuit and the active transistor, ensuring coplanar surfaces.
