  • Patent number: 9391350
    Abstract: Among other things, one or more techniques and systems for selectively filtering RF signals within one or more RF frequency band are provided. In particular, an RF choke, such as a 3D RF choke or a semi-lumped RF choke, configured to selectively filter such RF signals is provided. The RF choke comprises a metal connection line configured as an inductive element for the RF choke. In an example, one or more metal lines, such as a metal open stub, are formed as capacitive elements for the RF choke. In another example, one or more through vias are formed as capacitive elements for the RF choke. In this way, the RF choke allows DC power signals to pass through the metal connection line, while impeding RF signals within the one or more RF frequency bands from passing through the metal connection line.
