Title: Innovations of Sato Takahiro
Introduction
Sato Takahiro is a notable inventor based in Yokohama, Japan. He has made significant contributions to the field of electronics, particularly in the development of advanced communication technologies. With a total of 2 patents, his work focuses on enhancing power efficiency and signal processing.
Latest Patents
Sato's latest patents include a downconverter and upconverter, which are designed to achieve a sufficient image rejection ratio in low-Intermediate Frequency (IF) schemes while minimizing power consumption. These devices also suppress Error Vector Magnitude (EVM)-related degradation in zero-IF schemes. The downconverter and upconverter utilize a complex-coefficient transversal filter to reject 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. Additionally, a local oscillator outputs a real local signal at a set frequency, while a half-complex mixer performs frequency conversion by multiplying the complex RF signal with the real local signal, resulting in a complex signal with a frequency separated from the RF signal.
Another significant patent involves a terminal designed for low-power wake-up functionality. This terminal includes a passive filter that outputs a correlation signal between a received signal and a reference signal. A wake-up controller manages the activation of a communication module based on the correlation signal, allowing for power-efficient processing of wake-up signals. This innovation greatly reduces power consumption during the wake-up process.
