[REVIEW REQUEST] RF line of nrf54l15 circuit

Hello this is Bluetooth fingerprint processing circuit and i'm planning to order pcba for this.

But this is my first time designing with nrf54l15 and rf circuit. I'm so nervous that this circuit might not work.

I've already made poc with my nrf54l15 dk and All i want is feedback for rf line

Any comments are greatly appreciated.

I used IFA designed by TI. (Texas_SWRA117D_2.4GHz_Right). R10 and R9 is for tunning capacities. if no tunning required, R9 will be removed and R10 will be remain
