Andrey Knyazik

Electrical Engineer Iv @Applied Materials

Wrote Python code to automate the impedance measurement of motorized matching networks using vector network analyzer to map the impedance and characterize hysteresis.• Computed and simulated heating and impedance of various RF components. Designed, built, and tested physical setup to compare computations against experimental data.• Using microsecond scale data logger collected and analyzed data to characterize arcing during mixture of large RF and DC signals.• Collaborated with cross-functional teams to replicate customer process recipes to characterize various RF phenomena using oscilloscopes, vector network analyzers, and current probes.
