Title: Johnson Chau: Innovator in Radio Frequency Calibration

Introduction

Johnson Chau is a notable inventor based in Seattle, WA. He has made significant contributions to the field of radio frequency (RF) testing environments. His innovative approach has led to the development of techniques that enhance the accuracy of RF signal calibration.

Latest Patents

Johnson Chau holds a patent for "Radio frequency enclosure attenuation calibration." This patent discusses techniques for determining calibration data associated with an RF testing environment. The process involves inputting an RF signal into the RF enclosure and selectively applying it to discrete attenuators. These attenuators can adjust the strength of the signal, which can then be measured by various user equipment (UEs) located within the RF enclosure. By determining a plurality of measured reference signal received power (RSRP) values associated with specific attenuation levels, Chau's method allows for the extrapolation of measured attenuation steps to expedite the calibration process. This innovation ensures accurate signals for testing UEs.
