Patent ID: 7616676

Claim:
A combined ultrawide bandwidth-radio frequency (UWB-RF) remote identification tag, comprising: ultrawide bandwidth (UWB) circuitry for receiving or transmitting UWB signals; radio frequency (RF) circuitry for receiving or transmitting RF signals; and interface circuitry formed between the RF circuitry and the UWB circuitry, wherein the UWB-RF interface further comprises: a scaler for receiving a frequency signal from the RF circuitry, scaling it by a scaling factor P/Q, and providing a scaled frequency; a memory device for providing a data signal; and a mixer for mixing the scaled frequency with the data signal to form a UWB radio frequency signal, wherein the data signal includes one of identification data for the remote identification tag, date of placement of the remote identification tag, and information regarding an object that the remote identification tag is associated with, and wherein P and Q are integers and the UWB signals have a fractional bandwidth in the range of about 0.25 to 2.
