TX/RX time when using ADF7024

Hi,

My customer wants to transmit and receive 131bytes data using ADF7024.

How long does the overall transmission time when using the radio profile D?

If they use the radio profile E, How much can they reduce the overall transmission time than using D?

Thanks.

    Hi jhshin,

    To compute the total time to transmit, you would have to consider the preamble length, sync word, and CRC bits, together with the payload length.

    For a packet with 8 bytes of preamble, 3 bytes sync word, 2 bytes CRC, and payload of 131 bytes,

    total transmit time would be:

    ((8 bytes + 3 bytes + 2 bytes + 131 bytes) * 8 bits/byte) / Data Rate

    Time for radio profile D:

    ( (8+3+2+131) * 8 ) / 100kbps = ~11.52 ms

    Time for radio profile E:

    ( (8+3+2+131) * 8 ) / 200kbps = ~5.76 ms

    Actual transmission would have a small additional time for PA Ramp.

    Regards,
