Title: Kyu-don Choi: Innovator in RF Technology
Introduction
Kyu-don Choi is a prominent inventor based in Yongin-si, South Korea. He has made significant contributions to the field of radio frequency (RF) technology, holding a total of 2 patents. His work focuses on enhancing the performance and efficiency of RF signal processing devices.
Latest Patents
Choi's latest patents include an RF filter and a digital broadcast receiving tuner, as well as an RF signal processing device utilizing the RF filter. The RF filter is designed to include a band pass filter unit and an amplifying unit. When a signal with a frequency in a first band is input, the RF filter performs band pass filtering. Conversely, if a signal with a frequency in a second band is input, the RF filter executes an amplifying process. This innovative RF filter can be applied in various RF signal processing devices, such as digital broadcast receiving tuners. Additionally, he has developed a transmitter using a vertical BJT, which is capable of reducing power consumption, carrier leakage of a local oscillator, and error vector magnitude (EVM). This transmitter employs vertical BJTs implemented by a standard triplex well CMOS process in a frequency up-mixer and a baseband analog circuit, which includes a DAC, an LPF, a VGA, and a PGA, thereby enhancing the overall performance of the transmitter.
