Title: The Innovative Contributions of Andrew Kwan
Introduction
Andrew Kwan is a notable inventor based in Calgary, Canada. He has made significant contributions to the field of radio frequency (RF) technology, holding a total of 4 patents. His work focuses on enhancing the performance of RF amplifiers and linearized transmitters.
Latest Patents
One of Andrew Kwan's latest patents is titled "System and method for RF amplifiers." This invention involves a digital predistorter that includes a first predistorter for generating out-of-band and inter-band distortion components. This is designed to compensate for the static nonlinearity of a nonlinear element. Additionally, a second predistorter is cascaded with the first, which compensates for in-band distortion. Together, these components work to address in-band, out-of-band, and inter-band distortions when driven with multiband signals.
Another significant patent is the "Digital multi-band predistortion linearizer with non-linear subsampling algorithm in the feedback loop." This invention features a concurrent multi-band linearized transmitter (CMLT) that integrates a concurrent multi-band predistortion block (CDMPB) and a concurrent multi-band transmitter (CMT). The CDMPB consists of multiple digital baseband signal predistorter blocks (DBSPBs), an analyzing and modeling (A&M) stage, and a signal observation feedback loop. This innovative design allows for effective signal time alignment, reconstruction, and parameter computation for the DBSPBs.
