MediaTek
Analog / Mixed-Signal IC Engineer Intern
What I did
- Led post-silicon characterization of a zero-IF Wi-Fi 7 OFDM transceiver IC (DAC, ADC, RFFE).
- Tested Wi-Fi 7 EVM (4K-QAM) and ADC performance using vector signal generators and Keysight UXA.
- Measured spectral emission masks and root-caused digital spurs by comparing isolation on GND-variant chips.
- Optimized RX/TX validation benches, improving TX EVM by 6 dB and saving 2 hours per chip.
