Hi,

In the CC2590 datasheet pg6, dielectric thickness is 1-2:0.35mm, but in the reference design SWRR119 readme.txt,

it was 0.175mm. So Im confuse, which one to follow?

Can someone help to clarify this.

Thank you

Could you please send the link to the reference design that you are referring to?

Thanks.

Recently i bought the CC2541-CC290EM eval board, i tried to test the sensitivity of the board using Smartrf studio 7 V1.16. however i notice the HGM pin 9 of CC2541 does not go high even i selected the range extender and start the packet rx mode. the EN and PAEN works accordingly in the TX mode. could you let me know what goes wrong?

Thank you.
