Summary
👤
Senior🎓
Top SchoolChuck Duey is a versatile Hardware R&D Engineer with over three decades of mixed-signal and RF design experience and nine years in his current embedded Linux/RF roles. He has delivered production CMOS VCOs, DCOs and crystal oscillators across nodes from 90nm to 16nm finFET, and led lab and process deck setups for electromagnetic extraction and IC debug. At Keysight he blends analog/RF design with embedded Linux system security and instructional courseware, while his open-source contributions to the popular mraa project demonstrate hands-on platform support for Raspberry Pi and BeagleBone low-level I/O. Skilled at first-prototype analysis and PCB fabrication, he’s equally comfortable micro-probing a silicon die or soldering fine-pitch BGAs in a crowded RF test bench. A longtime Raspberry Pi hacker and instructor, he focuses on SPI/I2C/serial integrations and high-speed ADC work that bridges hardware bring-up and embedded software.
