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.
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.
RF capacitors have very high Q due to their low capacitance and very low ESR. Therefore, RF capacitors are often referred to as High Q capacitors. Since RF capacitors are often used for tuning and impedance matching applications, capacitance stability versus temperature is critical.
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).
KEMET’s HiQ CBR RF Capacitor Series features a copper electrode BME (Base Metal Electrode) system that offers ultra-low ESR and High Q in the VHF, UHF, and microwave frequency bands. Low ESR allows for higher RF currents which are ideal for various applications.
Knowing the four key characteristics of an RF capacitor, a definition can be provided. Definition: An RF capacitor is a capacitor that's "characteristics" are optimal at RF frequencies. Therefore, for RF capacitors, materials are chosen, and designs are optimized so that the capacitor’s characteristics are optimal at higher frequencies.
