Question

In the datasheet is can be found that L4 and L5 depend on the board size, but what values are used on the dev board (as a reference)? 

Answer 1

Hi KeeHog,

L4=12nH and L5=3.1nH. This is only applicable to our dev board.  They will need to be adjusted once the antenna and circuitry is developed into your device.

Hi Geoff,
And what are the L1,L2,C1,L3 values on SR4L049-EVB-3? Only to get the full circuit reference.

Regards.

L1= 3.3nH

L2= 3.3nH

C1= 1.8pF

L3= 3.3nH

These values are only a starting point to matching the antenna for your application.  The values will need to be adjusted.

Best regards,

Geoff S.
