Title: Hao-chung Chou and Radio-Frequency Calibration for Phased-Array Antennas.

Introduction

Hao-chung Chou is an inventor associated with Hsinchu, Taiwan, and Tron Future Tech Inc. His patent work includes a radio-frequency device designed to support power detection and calibration in phased-array antenna systems.

Latest Patents

Chou is associated with 1 patent: “Radio frequency device applied in phased array antenna with power detection and calibration, semiconductor device and method thereof.” The disclosed device includes a power amplifier, a power detector, and a digital signal processor. The power detector performs calibration operations at different bias voltages and generates corresponding calibration voltages. Because the detector’s electrical characteristics vary with temperature, the calibration voltages also reflect temperature effects. The digital signal processor uses calculations on those voltages to reduce temperature dependence in an index voltage representing the radio-frequency signal’s power, then adjusts the amplifier’s gain based on that index.

Career Highlights

Chou’s listed invention addresses power measurement and gain adjustment in radio-frequency systems. Its calibration approach is intended to improve the reliability of power detection despite temperature-related changes in the detector.
