Introduction

Song-cheol Hong is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of engineering, particularly in the development of advanced calibration circuits and beamforming systems. With a total of 11 patents to his name, Hong's work has had a substantial impact on technology.

Latest Patents

One of his latest patents is a calibration circuit designed for calibrating phases and gains between channels in a multi-channel beamforming system. This innovative circuit includes a selection unit, a power detector, an analog-to-digital converter, and a calibrator. The selection unit connects to multiple channels, selects two channels, provides a test signal, and receives a test result signal. The power detector measures the power of the selected channels, while the analog-to-digital converter performs A/D conversion on the output from the power detector. The calibrator then optimizes the phases and gains of the channels based on the converter's output.

Another notable patent is the variable gain phase shifter, which comprises an I/Q generator and a vector summation circuit. The I/Q generator produces phase signals based on an input signal. The vector summation circuit adjusts the magnitudes and directions of various in-phase and quadrature vectors, generating an output signal by summing these vectors. This invention enhances the precision and efficiency of signal processing.
