How Do Filters Work?
Jul , 02 2025
What Is an RF Filter? An RF filter is a passive or active component that allows signals within a certain frequency range to pass while attenuating signals outside that range. Filters are essential in both transmit and receive chains to isolate specific frequencies and prevent crosstalk, interference, or signal distortion. Types of Filters by Frequency Selection Depending on the application, filter...
