CC1311R3: antenna cuircuit for 868MHz design

Andy Lee

Part Number: CC1311R3

Hi,

I'm currently working on CC1311R3 5x5mm 2 layer 1mm PCB thickness PCB layout. May I ask the below balun setting is a suitable one? (refer to CC1311-R3EM-5XD7793)

Thx!

Yes, the schematic is suitable for 868/915 MHz ISM frequency bands.

Would recommend a 4-layer board instead of 2-layer board so that the unwanted emissions as low as possible

Thanks for the information.

PS: off-topic one: the placement location of the decoupling capacitors mentioned in the schematics is incorrect (perhaps it's a 7x7mm information, not 5x5mm)

Thanks. Yes this is from the 7x7 mm. Will update this.
