Abstract
Various arrangements of a nested radio frequency (RF) shield system are detailed herein. The system can include an internal RF shield that includes one or more tabs to be soldered to a printed circuit board (PCB). The system can further include an external RF shield that also includes tabs that are soldered to a PCB. When the internal RF shield and the external RF shield are installed on the PCB, protrusions of the shields nest together to block RF without requiring the shields be soldered together.

A nested radio frequency (RF) shield system, comprising:
- an internal RF shield, comprising:
- a first metallic housing;
- a first plurality of tabs to be soldered to a printed circuit board (PCB), the first plurality of tabs attached with the first metallic housing;
- and
- a first plurality of protrusions present on the first metallic housing, wherein when a first tab of the first plurality of tabs is inserted into the PCB, the first tab causes a first protrusion of the first plurality of protrusions to be pushed in a first direction;
- and
- an external RF shield, comprising:
- a second metallic housing;
- an RF connector attached with the second metallic housing;
- a second plurality of tabs to be soldered to the PCB;
- and
- a second plurality of protrusions present on the second metallic housing,
- wherein:
- each protrusion of the second plurality of protrusions extends to a bottom of a corresponding sidewall of the second metallic housing to allow the second plurality of protrusions to slide onto the first plurality of protrusions;
- when the internal RF shield and the external RF shield are installed on the PCB, the first plurality of protrusions and the second plurality of protrusions nest together;
- and
- when a second tab of the second plurality of tabs is inserted into the PCB, the second tab causes a second protrusion of the second plurality of protrusions to be pushed in a second direction, opposite direction from the first direction, against the first protrusion of the first plurality of protrusions.

A method for performing shielding of a tuner circuit, the method comprising:
- installing an internal RF shield by soldering a plurality of tabs of the internal RF shield to a printed circuit board (PCB), wherein when a first tab of the first plurality of tabs is inserted into the PCB, the first tab causes a first protrusion of a first plurality of protrusions to be pushed in a first direction;
- positioning an external RF shield onto the PCB such that the first plurality of protrusions of the internal RF shield and a second plurality of protrusions of the external RF shield nest together, wherein:
- when a second tab of the second plurality of tabs is inserted into the PCB, the second tab causes a second protrusion of the second plurality of protrusions to be pushed in a second direction, opposite direction from the first direction, against the first protrusion of the first plurality of protrusions;
- each protrusion of the second plurality of protrusions extends to a bottom of a corresponding sidewall of a second metallic housing to allow the second plurality of protrusions to slide onto the first plurality of protrusions;
- and
- when the internal RF shield and the external RF shield are installed on the PCB, the first plurality of protrusions and the second plurality of protrusions nest together;
- and
- after positioning the external RF shield onto the PCB, soldering a second plurality of tabs of the external RF shield onto the PCB.
