The GQM/GJM high-frequency ceramic capacitors are the best choice for high performance and high power RF designs requiring voltages up to 500V DC. These capacitors offer EIA sizes 0201, 0402, 0603, 0805, and the 1111 size with a capacitance range of 0.1pF to 100pF.
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.
These capacitors are usually ceramics, and some ceramic dielectrics like NP0/C0G have very high stability. Self-resonant frequency or ESL: These values might be specified on a design curve or provided directly in the datasheet. They could also be determined from an impedance curve.
These Murata High-Frequency Ceramic Capacitors feature low power consumption for mobile telecommunications, the GQM and GJM capacitors come with copper electrodes that allow for ultra-low ESR, high Q in the GHz frequencies, and high RF current handling capability.
In addition to the actual capacitance value, there is a short list of specifications to look at when selecting capacitors for high-frequency systems. Case size: Smaller case sizes tend to have higher self-resonance, and they can access smaller capacitance values (see below).
If you need discrete capacitors in a very high frequency board, then you need to account for these values in your circuit model. These values are determined by the following factors: The result is that the above curve is not necessarily observed once the components are placed on a real PCB.
