An electronic jamming circuit and method used to place a protective area around a person or vehicle so that an explosive device cannot be triggered are described. A wideband code division multiple access (WCDMA) device in proximity to an explosive device is prevented from being triggered by a WCDMA communication by disruption of the ability of the WCDMA device to synchronize with, and thus cannot decipher, the communication. The jammer device may operate by forcing timing circuits in the WCDMA device to lock onto a jamming signal.
