Flex PCB stackup for NRF52840-QIAA-R7 antenna design and LC values

[purushothama.pa]

what is the correct stack up required for Flex PCB  for NRF52840-QIAA-R7 antenna design and LC values.

[Kaja]

We don't have separate requirements/recommendations for FLEX pcb. Use te same stack up, and the same reference design. 


The components values for the radio matching must be tuned for the specific design, no matter the substrate used.  

Best regards,
