An electronic device ( 400 ) enabled to receive radio frequency signals can comprise a housing ( 405 ), a PCB ( 110 ) enclosed in the housing ( 100 ), an antenna ( 115 ) coupled to the PCB ( 110 ) and enabled to receive the radio frequency signals and a choke ( 125 ) coupled to the PCB ( 110 ) and enabled to suppress radio frequency currents flowing on the PCB ( 110 ). As an example, the frequency at which the choke ( 125 ) suppresses the currents can be at a GPS signal frequency.
