Knowles Precision Devices Datasheets for DC Blocks
DC blocks prevent the flow of direct current (DC) through radio frequency (RF) circuits. They serve as high-pass filters that prevent DC voltages, which have a frequency of zero Hertz (Hz), from interfering with sensitive RF components such as receivers. In other words, DC blocks are capacitors in series with a transmission line. They prevent the flow of DC energy while allowing RF signals to pass with little (if any) attenuation.
