First series resonance (FSR) and first parallel resonance (FPR): These are the lowest rated frequency value at which S11 and S21 are rated for the capacitor in question. Here are two excellent sets of high frequency capacitors that are ideal for applications in the GHz range:
At low frequency, the impedance provided by the capacitor is dominant, and your capacitor will exhibit close to ideal behavior. At sufficiently high frequency, the ESL value takes over, and the impedance starts to appear inductive. This produces an effect known as self-resonance at just the right frequency.
About High-Frequency Capacitors High-frequency capacitors are marketed as such due to their ability to retain ideal capacitive behavior up to very high frequencies. Capacitors will not exhibit ideal behavior up to the intended operating frequencies in RF systems, even if they are marketed as “high-frequency” or “RF” components.
Equivalent high frequency capacitor model. This means that the important characteristic distinguishing different capacitors for different frequency ranges is the capacitor’s self-resonant frequency. At this particular frequency, the capacitor will exhibit its minimum impedance and a very strong current response.
In the capacitive characteristic region, the larger the capacitance, the lower is the impedance. Moreover, the smaller the capacitance, the higher is the resonance frequency, and the lower is the impedance in the inductive characteristic region. Our explanation of the frequency characteristics of capacitor impedance may be summarized as follows.
In other words, the self-resonant frequency should be greater than the knee frequency. With high frequency analog signals, any capacitors should be chosen such that the relevant frequencies in the system are lower than the self-resonant frequency.
