Off-the-shelf “flying lead” and surface mount broadband conical inductors, Figure 1 and Figure 2, are a special type of broadband RF choke that are used to filter radio frequency (RF) and microwave frequency interference from electronic circuits. At high frequency, the RF choke becomes a high impedance element used to isolate noise or DC from desired signals.
