Using 0402 instead of 0201 for RF front end matching.

[anthony32086]

The reference design for the nRF5340DK uses 0201 components for the matching network.

Would it be acceptable to replace the 201 matching network components to 0402 parts while keeping the same value and tolerances.

Then only adjusting the microstrip width to maintain minimal stubs and 50 ohms or will the addition of a larger package require additional front end output impedance tuning?

Hi

We generally don't recommend switching to 0402 components, but it should work okay. Please note that you will need to tune the values/tolerances of these components as it will not be a 1-to-1 change. You might also have trouble following the reference layout when doubling the sizes of these components. 

Best regards,

Simon
