摘要： In accordance with a non-limiting aspect, a mobile wireless communications device includes a housing, at least one circuit board carried by the housing, radio frequency (RF) circuitry, and a processor. An antenna is operative with the RF circuitry. A charging circuit charges a battery carried by and powers the device and includes at least one charging contact carried by the housing and configured for engaging an external charging cradle when connected thereto. It includes an internal connector extending to at least one circuit board and connecting to the charging circuitry. An RF filter includes a ferrite material surrounding at least a portion of the internal connector to minimize RE coupling from the at least one charging contact to the antenna and reduce transmitter harmonics emission and receiver de-sense.
