AWR1243: Rogers 4835 LOPRO

Part Number: AWR1243

Hi

We have a problem when referring to the awr 1243p demo design.

Compared with Rogers 3003, what are the benefits of Rogers 4835 LOPRO?

Why the third layer uses Rogers 4835 LOPRO?

    Hello,

    The primary benefit of Rogers 4835 vs 3003 is cost. The 4835 laminate is much cheaper and also has shorter lead times compared to the 3003 laminate. 

    If cost is not a concern, the 3003 laminate will always perform better than the 4835 laminate. The 3003 has lower loss and is more consistent over temperature, so you should choose to use 3003 over 4835 if it is an option.

    Can you clarify which design you are referring to where the third layer is using a rogers laminate? This is usually only used on the top layer (or bottom, whichever is the antenna layer).

    Regards,

    Adrian

    Hello,

    Thank you for your answer.I am referring to the Rogers laminate used in the third layer.

    One more question needs to be consulted,the high power of multiple cascade chips will not affect the characteristics of the first layer using Rogers 3003 laminates.

    After of all,3003 laminate is only 5 mil thick and has a soft texture.

    Hello,

    We have not seen any issues with heat affecting the rogers laminate, though you are right the rogers laminate layer is much softer. 

    I am not too familiar with the cascade design, so I am looping in our cascade expert to comment.

    Regards,

    Hi ,

    You can reference the Rogers substrate datasheets to answer your material stability questions: https://rogerscorp.com/en/advanced-connectivity-solutions/ro3000-series-laminates/ro3003-laminates

    These materials are characterized across temperature ranges which exceed the min/max of our own components.

    Please consult with Rogers documentation and sales support for further questions about these materials.

    Thank you,
