Title: The Innovations of Jae Hwan Im
Introduction
Jae Hwan Im is a notable inventor based in Gwangmyeong-si, South Korea. He has made significant contributions to the field of signal modulation, holding two patents that showcase his innovative approach to technology. His work primarily focuses on vector modulators, which are essential in various communication systems.
Latest Patents
One of Jae Hwan Im's latest patents is a vector modulator that can control the amplitude and phase of an input signal without using amplitude variable attenuators. Instead, it employs phase shifters, resulting in a simple configuration that allows for precise modulation of the input signal. This vector modulator can modulate the phase of an input signal across all areas in the polar coordinate system.
Another significant patent is a vector modulator that utilizes time delay and phase shifters. This invention includes a time delay that varies the phase of an input signal by delaying it. The first coupler converts the signal outputted in a changed phase through the time delay into I and Q channel signals, each having a 90° phase difference. The first and second phase shifters then vary the phases of the I and Q channel signals, respectively, before they are coupled and outputted.
