Abstract
A mobile wireless communications device includes a housing and circuit board carried by the housing and having RF circuitry comprising at least one RF component and plurality of other components mounted on the circuit board. An RF metal shield is secured to the circuit board and surrounds and isolates the at least one RF component and plurality of other components within the RF metal shield. An RF absorber is positioned adjacent an area of the RF component that radiates energy to aid in reducing energy radiated from the RF component into the RF metal shield.
