WebFeb 2, 2024 · An RF choke (radio frequency choke) is a type of inductor, but it differs in its application, function, and design. An RF choke uses frequency selectivity to allow the passage of low-frequency DC signals while blocking high-frequency AC signals such as radio frequency. To do this, the RF choke has a high impedance over the range of frequencies ... WebRF chokes, such as conical inductors, are employed in electrical circuits to reduce EMI by attenuating high-frequency noise in order to meet EMC emission and immunity requirements. A broadband (wideband) conical bias choke placed in line with the DC bias of an amplifier blocks a wide range of high frequencies from reaching the DC source.
