Hi TI!
I have a design based in CC1352P.
I am using the Integrated Filter Balun for CC1352: 0900PC15A0036 and the antenna switch SKY13317-373 (the same gpio control as the CC1352P2 launch pad).
The same Antenna pcb antenna that lauchpad CC1352.
The design no comunicate by RF.
My problem can be in the RF shematic design or RF layout.
The Sub 1GHz channel isn't used.
I did try to kept the RF tracks as short possible with a width 8.89 mil and and a height from the solid gnd plane of 5 mm (with this values the RF tracks has 50 ohm theorically ).
The solid ground plane is next layer to the top layer.
The distance between CC1352 and 0900PC15A0036 is 1.26 mm
Attached the RF shematic design and RF layout.
Please, there are any Idea about the reason of my problem?
