Introduction Capacitors are equally vital in RF and microwave circuits, enabling critical functions like DC blocking, impedance matching, and harmonic filtering. However, their high-frequency performance is constrained by parasitic inductance inherent in real-world implementations. For capacitors, the self-resonant frequency (SRF) marks the point where parasitic inductance resonates with the intended capacitance, transforming the component into […]

Inductors are indispensable components in RF and microwave circuits, playing crucial roles in filtering, impedance matching, and signal tuning. However, their behavior at high frequencies is far from ideal due to inherent parasitic elements that limit their performance. One key parameter that defines the usable frequency range of an inductor is its self-resonant frequency (SRF)
