IWR1443: High-frequency performance

Part Number: IWR1443
Other Parts Discussed in Thread: IWR1843

Hi!

IWR1443 and IWR1843 are the same generation of MMICs, but what differences do you see in the performance of the high-frequency part?
Are there any differences in Tx characteristics or Rx sensitivity? If so, which is superior?

Thanks

    Hello,

    Thank you for reaching out to Texas Instruments. We are working on your query and will respond by the next business day.

    Hello,

    There is no way of characterizing one device as superior to the other. Both the radars have the capability to detect near and far away objects with mm accuracy. Following are a few differences between the devices.

    • IWR1843 has DSP onboard, IWR1443 doesn't. 
    • IWR1443 can be used for low-power applications. 
    • IWR1843 has an on-chip memory of 2000KB whereas IWR1443 has 576KB.
    • Max IF for IWR1443 is 15MHz and that for IWR1843 is 10MHz
    • IWR1443 has a higher sampling rate of 37.5 Msps when compared to 25Msps of IWR1843. 

    Your application will decide which device is better suited. 

    Hope this helps,

    Thank you for your answer.
    The customer uses Raw data to evaluate the algorithm. Is it correct to assume that there will be no significant difference between the two ICs when used under the same conditions?

    Best Regards

    Hello Akira,

    Both the ICs will give you RawData that can be analyzed for further evaluation. But to answer your question, I would need to understand what you are trying to do with the IC.
