RFID SAW Reader

Hello,

I am constructing a RFID reader for passive SAW tags. The central frequency is 915MHz aprox. and the bandwidth is 40MHz. The saw tag receive an RF burst signal that last no more than 20 ns, then the tag sends a signal with the information throught RF pulses which have a width of 20ns aprox. I'm considering use the ADF9010 Eval board to this purpose. ¿Would you recommend me this board or should I look for another device?

  • The ADF9010 is designed as an RF front-end for an RFID reader system compliant to the EPC global

    RFID standards and can operate across a range of 840MHz to 960MHz.

    Figure 27. gives the applications diagram of the full transceiver which you would need to interface

    to a DSP for baseband processing. The ADF9010 eval board contains the ADF9010, the Rx demod

    chip (ADL5382) and a connector to an MxFE board. The recommended MxFEs are the AD9863.

    or AD9963.

    The ADF9010 has programmable Rx bandwidths of 320k/1M/2MHz.

    when you say a BW of 40MHz I assume you mean the full channelized bandwidth and the

    channel bandwidth is less than this ? You would need a max. channel size of less than about 2.5MHz

    with the 2MHz filter BW.
