RF & Software-Defined Radio Systems
A collection of RF design, embedded communications, and SDR work covering filters, impedance matching, signal analysis, and wireless firmware.

Overview
This page is the working case-study shell. We’ll replace this text with the exact problem, requirements, constraints, and scope from your project.
The goal is to make the engineering readable in under a minute, then provide enough depth for a technical interviewer to keep digging.
System Architecture
RF Design: Requirements → ADS Filter / Matching Network → Simulation → Bench Evaluation\nSDR: RF Signal → SDR Front End → Spectrum / IQ Data → MATLAB / Software Processing\nEmbedded Wireless: SAMD21 Firmware ↔ LoRa Radio ↔ Wireless Link
My Contribution
- Designed and simulated RF filters and impedance-matching networks in Keysight ADS.
- Worked with SDR-based signal acquisition/analysis workflows.
- Developed embedded LoRa communications firmware and evaluated RF behavior with lab instrumentation.
Photos, Schematics & Test Evidence
PLACEHOLDER
Add real hardware photos, block diagrams, scope captures, ADS plots, terminal screenshots, CAD, or test data here.

Integration & Debugging
We’ll show where simulation, expected behavior, and measured behavior differed—and how you investigated those differences.
Results & Validation
Add ADS S-parameter plots, Smith charts, filter response, SDR waterfall/spectrum captures, and bench-test results here.
