nRF54L15 layout for rf part

[Webster Yang]

Dear Nordic Team : 

1. Are the T-matching (L2/C6/L3) for IC matching and the pi-matching network(C9/L4/C11) for antenna?

2. If we have long trace for the antenna, should the pi-matching be close to antenna side?

2. If the pi matching is close to the antenna side, should the C9 need to be the as the guideline?

3. If we are planning to use +8dBm for bt tx power, could we use the same matching topology?

All components in the "box" in the ref schematic are for the matching network, antenna tuning components comes in addition to this.

If we have long trace for the antenna, should the pi-matching be close to antenna side?

Yes

3. If we are planning to use +8dBm for bt tx power, could we use the same matching topology?

Yes, all components are mandatory for all power levels.
