Abstract

A mobile wireless communications device includes a circuit board carried by a housing and having RF circuitry and a processor operative with the RF
circuitry. A keyboard is carried by the housing and includes a keypad array circuit. A keypad connector is carried by the keypad and is operatively connected to the RF circuitry and processor. A plurality of Key Out and Key_In connection lines connect the keypad connector and keypad array circuit.
Filters carried by the keyboard are connected into each Key Out and Key In connection line for reducing RF energy picked up from either the antenna or external interference and interfering with normal processor operation.
