Filter: High-frequency Pass

Want to extract high-frequency components from a mixed-frequency signal? Try the high pass inductor filter! It is like a precise "frequency traffic alert" : the capacitor lights up a red light for low frequencies (high impedance), and the inductor turns a green light for high frequencies (low impedance). In a typical LC structure, when the current through an inductor exceeds 10 MHZ, the inductive reactance drops sharply to less than 1Ω, allowing the radio frequency signal to pass easily. The 50Hz power frequency interference is intercepted by a hundredfold impedance. This type of filter acts as the gatekeeper of RF devices, ensuring that the signal is "free of impurities and retains the essence" from radio transceivers to Bluetooth modules. When designing, it is necessary to calculate the resonant point to avoid self-excitation between the filter inductance (such as 22μH) and the capacitor.
