Title: Innovations of Chia-sam Wey
Introduction
Chia-sam Wey is a notable inventor based in Arlington, TX (US). He holds a total of 7 patents that showcase his contributions to the field of technology, particularly in power amplification and control systems.
Latest Patents
One of his latest patents is a combined RF power detector and power precorrector. This invention addresses the non-linear characteristics of power amplifiers (PAs) that result from Amplitude Modulation-Phase Modulation (AM-PM) conversions, which can lead to intermodulation issues affecting the RF signal spectrum. The invention presents a method and apparatus designed to reduce intermodulation generated at the output of a PA due to AM-PM conversion. The RF power detector utilized in this invention includes a detector input for receiving RF power and a detector output that contains a pre-corrected detected voltage. Additionally, it features a pre-correcting circuit that generates odd-order harmonics at a specific power level, allowing the feedback control circuit to compensate for AM conversions.
Another significant patent focuses on improving the loop stability and speed of a power control loop. This invention aims to reduce adjacent channel interference during the transient phases of a TDMA burst. By adjusting the loop bandwidth, the invention enhances both the stability and speed of the power control loop. A reference signal is sampled and processed to set the gain of the feedback loop, which ultimately increases the lower loop bandwidth for speed and decreases the upper loop bandwidth for stability.
