摘要： A resonator may include a first terminal, a second terminal, a resonator between the first terminal and the second terminal, and a reactive element in series with a switch. The reactive element in series with the switch may be connected in parallel with the resonator. The resonator may provide a first set of resonance frequencies when the switch is operated in a non-conducting state and a second set of resonance frequencies when the switch is operated in a conducting state.

摘要： One way to stop electromagnetic fields from leaking outside of a module is an electric wall. Embodiments of the present disclosure are directed to emulating an electric wall with through vias. The through vias may be arranged around cavities in the printed circuit board. The density of the through vias may be selected based on an expected wavelength of the electromagnetic fields. The printed circuit board may then self-isolate components within the cavities from the electromagnetic fields.
