CC1350: Question about the CC1350 reference schematic

Dorian Levy

Part Number: CC1350

I am designing a project using the CC1350 for BLE and Sub 1GHz. I am following CC13xxEM-5XD-DualBand(a0132610) drawing as a reference. I noticed that RF_N is connected to PORT1+ and RF_P is connected to PORT1-. Is this correct? If it is correct what is the reasoning? 1350 Schematic.pdf

Hi Dorian,

RF-P and RF-N on the CC1350 are interchangeable. The switch is passive and does not really care about polarity either. The connection is made this way to avoid crossing the RF traces.

Cheers,
Fredrik
