What value resistor would I piggyback onto R10 to target 1.30V, or 1.25V?
For 1.3V (1.278V under load) I use 47k. No problem with 400MHz and 0.98% HW, Rejected 0.38%
For stability I suggest sold 2mm
2 wire from coil to the end of board. Top cooper layer (VDD_1.2) is too thin to carry such high currents.
Look on the picture below
