Title: Innovations by Lawrence Wong
Introduction
Lawrence Wong is a notable inventor based in Markham, Canada. He has made significant contributions to the field of radio frequency (RF) technology, holding three patents to his name. His work focuses on overcoming challenges in RF signal processing, particularly in modulation and demodulation.
Latest Patents
One of his latest patents is titled "Method and apparatus for up-and-down-conversion of radio frequency (RF) signals." This patent describes a method and system that addresses the local oscillator (LO) leakage problem commonly encountered in direct conversion and similar RF transmitters and receivers. The invention utilizes a virtual local oscillator (VLO™) signal that emulates mixing with a local oscillator signal. The VLO signal is constructed using complementary mixing signals that suppress mixing power within the bandwidth of both the input signal and the output frequency. Specifically, the mixing process occurs in two or more stages, employing time-varying mixing signals that meet specific criteria to ensure effective performance.
Another patent under his name is also titled "Method and apparatus for up-and-down-conversion of radio frequency (RF) signals." This invention similarly addresses the LO-leakage issue by generating a virtual LO signal that does not contain significant power at the desired output RF frequency. This innovative approach eliminates the need for sophisticated filters or large capacitors, making it fully integratable into existing systems.
