The LTC6602 dual bandpass filter, a programmable baseband filter for high performance UHF radio frequency identification (RFID) readers, is described.
Radio frequency identification
Radio frequency identification (RFID) is an auto-ID technology that identifies any object that contains a coded tag. A UHF RFID system consists of a reader (or interrogator) that transmits information to a tag by modulating an RF signal in the 860MHz–960MHz frequency range. Typically, the tag is passive—it receives all of its operating energy from a reader that transmits a continuous-wave (CW) RF signal. ...
