Hi Team,
customer has some question, please kindly support it.
thanks!!!
Hello, during the process of using CC2640F128RHB, we found that the signal transmission distance of CC2640 was very close, so we would like to consult the following two questions:
1， Can the RF part of CC2640 add PA? SCH sees the attachment. Please help to evaluate whether the added PA is compatible with CC2640？
2， According to the information found, our solution is as follows. Please help to evaluate whether the solution is feasible or not.If the scheme is feasible, we need your help to provide the functions that control the receiving time and sending time at the bottom of the software. Please tell us what is the interval between the sending time and the receiving time?What we have found is that there is a gap between receiving time and sending time described in connection parameters, so the current scheme is to open and close PA(SKY66114) according to the gap between receiving time and sending time.The truth table in the PA data sheet is used to control different modes.As shown in the figure below:

Hi,
Why can't you use CC2592 instead of SKY66114-11?
We have a Reference Design with CC2650+CC2592. The following is the link to our reference design. Please follow the reference design and make the changes accordingly.
If you still wants yo use SKY66114-11 then please copy the CC2640 portion ( including Power Supply Filter and all the De-Coupling Caps) of the Schematic from our Reference Design SWRC303. The following is the link to the design files ( Murata Balun). I observed missing Power Supply filter and some De-Coupling Caps on your CC2640 circuit.
Thanks,
PM
