Abstract
Electrically-conductive wires are used to construct an EMI shield between inductors of an RF module that prevents, or at least reduces, EMI crosstalk between the inductors while maintaining high Q factors for the inductors. The EMI shield comprises at least a first set of electrically-conductive wires that at least partially surrounds and extends over at least a first inductor of a pair of inductors. Adjacent wires of the first set are spaced apart from one another by a predetermined distance selected to ensure that the EMI shield attenuates a frequency or frequency range of interest. First and second ends of each of the wires are connected to an electrical ground structure. A length of each wire in between the first and second ends of the respective wire extends above the first inductor and is spaced apart from the first inductor so as not to be in contact with the first inductor.
