Chak M Chie is a notable inventor based in Culver City, CA, with a significant contribution to the field of phased-array antenna technology. He holds a total of seven patents, showcasing his expertise and innovative spirit in this specialized area.

Latest Patents

Chak M Chie's latest patents include "Hierarchically elaborated phased-array antenna modules and method of operation." This invention describes a phased-array antenna panel with front-end modules mounted on a Printed Circuit Board (PCB). The system incorporates several phased-array processing dies that transform phase and gain according to a register array in an RFIC on the PCB. The register array is organized into local and global register groups, where local registers control individual antenna elements, while the global register group manages the overall RFIC function. This apparatus enhances the capability to accelerate antenna beam direction changes by elaborating phase shift weights into a submodule of the phased-array antenna system.

Another significant patent is "Hierarchically elaborated phased-array antenna modules and faster beam steering method of operation." This system updates all phase shifter values of a phased-array antenna using two 'global writes' to simultaneously update parameters across all phased-array transformation circuits via a serial bus. Each antenna element is controlled by a phased-array transformation circuit, which is configured to transform phase and gain according to a register array. The local registers are strategically placed near RF chains corresponding to each antenna element, allowing for efficient control of individual elements and overall beam steering function.
