What is a RF filter?
A filter is an element or circuit that discriminates frequencies and allows only signals in the required frequency band to pass while blocking other signals, and is classified into low-pass filters (LPF), band-pass filters (BPF), and high-pass filters (HPF). What is an RF filter? Radio Frequency: A filter for broadcast waves and wireless communication signals using high frequencies. Digital terrestrial broadcasting uses signals in the frequency band of 80 to 800 MHz. Mobile phones such as smartphones use signals in the frequency band of 800 to 3500 MHz. Therefore, RF filters are used, for example, to block signals outside the frequency band of these broadcasts and communications.
