Abstract
An apparatus and method for coupling a radio frequency identification (RFID) integrated circuit (IC) with a dual loop coil formed on a lead frame. In one embodiment, the lead frame is encapsulated in an IC package.
Claims20
An apparatus, comprising:
- a radio frequency identification (RFID) integrated circuit (IC) having a first terminal, a second terminal, a third terminal, and a fourth terminal coupled to a surface of the RFID IC;
- a lead frame having a first coil segment and a second coil segment, wherein a first end of the first coil segment is coupled to the first terminal, and a second end of the first coil segment is coupled to the second terminal;
- wherein a first end of the second coil segment is coupled to the third terminal, and a second end of the second coil is coupled to the fourth terminal;
- and
- a resistive interconnect having a first end coupled to the first terminal, and a second end coupled to the third terminal, the resistive interconnect being formed within one or more layers of the RFID IC.
