433 MHz RF Design & Measurement
A collection of projects that moved repeatedly from RF theory and ADS simulation to fabrication, VNA/spectrum-analyzer measurement, comparison, and redesign.

OVERVIEW
What I built
The RF work includes a low-noise amplifier, Wilkinson divider, stepped-impedance low-pass filter, mixer and antenna characterization, SDR experiments, and an end-to-end transceiver laboratory.
ENGINEERING WORK
What the project demonstrates
- ADS schematic, matching-network, and transmission-line design.
- VNA measurement of S11, S21, return loss, insertion loss, impedance, and isolation.
- Spectrum-analyzer measurement of IF, LO, RF, mixer products, and filtering.
- Real-hardware comparison against simulated performance and analysis of parasitics.
- Hands-on RF fabrication and troubleshooting.
