Extraction of lumped elements parameters using VNWA

VNWA3E has special functions to extract the lumped elements parameters of circuits or some components.  Today, I will explain how to use this functions with the following 1 [nF] ceramic capacitor. First, I measured the S11 parameters and other parameters using the special tool which is designed for through-hole components.  We can easily expect that component wire produces parasitic inductance, which results in some resonance at some frequency. The following figure shows the measurement results. The frequency range is from 1 MHz to 60 MHz. The blue line is S11 [dB]. The Yellow line is capacitance value which is calculated from S11. The magenta line is  real value of the […]
