ESP32-C6 RF pin output impedance

[kefecik]

Hello there,
I am pretty new to pcb design and rf. I am designing a board with ESP32-C6 QFN40 package.I know that I need to match the impedance to 50 ohms but I can not find the impedance of PIN 1 (ANT) explicitly mentioned anywhere? This is my current board for reference, if you see any obvious mistakes.

Keep in mind that there should be no ground pour or traces under/near the antenna area.

Is D2 going to put 11V on the USB connector?

No it will be reverse biased if 12V is connected.
