I refer to document TIDUDQ6.pdf – December 2017 which is the reference design document for TIDA 01570.
Please refer to page 18, section 5.3.2
It states that "This design uses Rogers ceramic materials"
However the diagram below depicting the board stack up is using 370HR dielectric. Which is from ISOLA.
Can you let me know whether it indeed used 370HR with the stack up mentioned.
If yes can you provide any ball park figure on received signal strength between this board and the one like AWR1642boost which is using a mixed substrate with Rogers LoPro.
