IWR1443: The differences between IWR1443 and AWR1243 RF specifications

Part Number: IWR1443
Other Parts Discussed in Thread: AWR1243

What are the differences between IWR1443 and AWR1243 RF specifications?

Our customer wants to use AWR1243 with multichip cascading (20-GHz sync) in non-automotive applications. By comparing the data sheets of IWR1443 and AWR1243, there seems to be no differences between their RF specifications. If so, IWR1443 should be used rather than AWR1243 in non-automotive applications.

Is my understanding correct?

Best regards,

Daisuke

    Daisuke,

    You are exactly correct! AWR1243 contains the entire Radar Front End (RFE) that you are going to find in the IWR1443 which includes a Hardware Accelerator for FFT Processing. The IWR1443 is going to be preferable for non-automotive applications a vast majority of the time.

    Let me know if you have any other questions.


    Cheers,
    Akash

    Hi Akash-san,

    Thank you for your reply.

    In what cases for non-automotive applications is the AWR1243 preferable?

    The IWR1443 has the same radar characteristics and performance, more features, and lower price as/than the AWR1243. The IWR1443 should be preferable in all cases for non-automotive applications.

    Best regards,

    Daisuke

    Hello Daisuke,

    Apologies for the delay. As of right now we do not recommend using the AWR1243 for any non-automotive application and would immediately recommend using the IWR1443.

    Since all of the processing can be done on the IWR1443, this is what makes it preferable. The same cannot be said for AWR1243.

    Hi Akash-san,

    Thank you for your reply.

    Are there any differences between IWR1443 and AWR1243 in radar characteristics/performance that is not documented?

    Our customer application uses long range radar (LRR). We talked to third party who is familiar with TI mmWave devices and specializes in automotive applications. They recommended AWR1243 rather than IWR1443. They say AWR1243 is preferable for LRR because it has better radar characteristics/performance than IWR1443.

    Hi Akash-san,

    The difference between IWR1443 and AWR1243 in radar characteristics/performance may be based on the experimental results by the third party, so first I'll ask the third party for the detail.
