About Me

Building at the Intersection of RF & Silicon

M.Eng. ECE · Oregon State University

I'm a Master's student in Electrical and Computer Engineering at Oregon State University, specializing in RF/microwave circuit design and analog IC design. I've designed and characterized coupled-line filters, low-noise amplifiers, and CMOS amplifiers — working from schematic and EM simulation through lab characterization on VNA and spectrum analyzer.

Outside of circuits, I love using AI tools to build — whether it's scripting test automation, prototyping ideas, or building this site itself. I think the engineers who combine hardware depth with AI-assisted workflows will define the next decade.

Selected Projects

RF/Microwave

Coupled-Line Microstrip Bandpass Filter

Designed a 3 GHz BPF in ADS and HFSS: translated prototype element values into physical coupled-line dimensions, iterated layout via S11/S21 results, and characterised the fabricated board with a VNA, spectrum analyser, and RF source.

Noise-Cancelling LNA Design (5G/Wi-Fi 6)

2.4 GHz LNA for 5G/Wi-Fi 6 front-end modules with input/output matching using Smith-chart tuning.

  • Designed a 2.4 GHz LNA for 5G/Wi-Fi 6 front-end modules with input/output matching using Smith-chart tuning.
  • Performed transistor sizing, biasing, and input/output matching using Smith chart-based tuning.
  • Evaluated RF metrics in simulation: 11.5 dB gain, 0.94 dB NF, −14 dB S11, −15 dB S22, 4.1 dBm IIP3; documented gain/NF/matching trade-offs and design rationale.
