CC26xx + CC2590 Reference Design

The design is not on the web yet. We have a preliminary version that has good results this far. The preliminary design keeps the CC2640 part as is (except for the RF pins), and follows the CC2541-CC2590EM reference design for the CC2590-part. The matching between the CC2640 and the CC2590 is an inductor between RF_N and RF_P pins, but this inductor is currently not mounted. If you send me a friend request, I can provide you with the preliminary design. 

Do you mean www.ti.com/.../TIDC-CC2650-CC2592-EMK is not a fine tuned reference design for CC26xx with CC2593 as PA/LNA?

The CC2590 and CC2592 are not pin compatible and have different external comp and filtering. The design you refer has very good performance for the CC26xx and CC2592 combination. The CC2592 however has a much higher gain than the CC2590 and is not optimal for BLE since the max output power for BLE is 10 dBm.

I see and Thanks.

Hello Charlotte,

Any update regarding when is the 2650+2590 reference design expected to be ready?

Thanks,

Hi Yuval,
Unfortunately the design has been delayed due to prioritization.

If you search the forum you should find a bit of information to help you with the design.

Cheers,
Fredrik
