Latest Patents

Won-Jin Baek holds a patent for a downconverter and upconverter. This invention is designed to achieve a sufficient image rejection ratio in a low-Intermediate Frequency (IF) scheme while reducing power consumption. It also addresses the suppression of Error Vector Magnitude (EVM)-related degradation in a zero-IF scheme. The technology involves a complex-coefficient transversal filter that rejects one side of a positive or negative frequency, converting a Radio Frequency (RF) signal into a complex RF signal composed of real and imaginary parts. A local oscillator outputs a real local signal with a set frequency, while a half-complex mixer performs the frequency conversion process, resulting in a complex signal that is separated by the set frequency from the RF signal.
