AWR1843BOOST: Can use material RO4450F instead of Rogers4835 material for custom board as similar to AWR1843 boost EVM

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843,

Tool/software:

Hi all,

Can use material RO4450F instead of Rogers4835 material as PCB fabricator suggested as per their availability for custom Sensor board which includes the AWR1843 and antenna design?

Is any performance Issue happed with Antenna detection range and/or cross section detection, heat Loss or anything else.

Please Confirm can we use material RO4450F use for AWR1843 and Antenna in place of Rogers4835Rogers4835 in AWR1843 boost layer stack up.

    Hi, 

    We cannot confirm if it will work or not. You will need to simulate the model on HFSS and possibly re-tune the transitions with the new material.

    Does your company have NDA signed with TI? Once that is done, we can provide our encrypted HFSS model, and you will need to change the material and simulate the parameters to confirm. 

    Regards,

    Aydin

    1) If possible, simulation can be done by TI team on (HFSS) high-frequency structure simulator and if required re-tuning the transition of RO4450F material with reference design of AWR1843boost or our custom board and share result with us.
    2) Other option as per suggestion you can provide support with guidelines on encrypted HFSS model to change material and simulated parameter by us. (For that we already have NDA with TI). But performing the HFSS model we don't have any HFSS tool, can we get online tool support for that or anything else can be possible.

    Hi Pradip,

    Customers are responsible for the simulation in case of any changes. Unfortunately, we do not have any guidelines to provide on HFSS. However, we'd be happy to assist you with the board's schematic/layout reviews if needed.

    Regards,
