Patent ID: 8649184

Claim:
A dual chip signal conversion device, comprising: a carrier comprising a first substrate, a second substrate and a connecting portion for connecting the first and second substrates, one side surface of the first substrate being provided with at least a first contact and a second contact while the other side surface of the first substrate being provided with at least a third contact and a fourth contact, there being an electrical connection between the first and third contacts; a first chip disposed at one side surface of the carrier and electrically connected to the second and fourth contacts; a second chip disposed at one side surface of the carrier and electrically connected to the first chip; and an antenna disposed within the second substrate and electrically connected to the second chip, wherein the first substrate is used to be attached to a SIM card; and wherein the one side surface of the first substrate is coated with an adhesive material so that the one side surface of the first substrate can be adhered to the SIM card.
