Hello,
I am developing a custom board with the STM32WB55RGV6 Chip and an on-board PCB antenna. The document is for a 2-layer PCB and I am needing to do a 4-layer PCB. I don't completely have the recommended stack-up, but altium shows its very close to 50Ohms. Will this work?

Here is the RF routed. Please advise if you see anything needing corrected.

I just beefed the RF traces up to 15mils--other than the antenna which is to spec--, do I need to be more specific for impedance matching?

You may have a look at applications notes AN5290 and AN5165 where you can find information on Table 4. 4-layer PCB and on the matching network.
