发明名称 MOBILE WIRELESS COMMUNICATIONS DEVICE WITH REDUCED INTERFERING RF ENERGY INTO RF METAL SHIELD SECURED ON CIRCUIT BOARD
摘要 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 lea st one RF component and plurality of other components within the RF metal shield.
