The typical voltage of 3.8V is recommended. Schematic suggestion: We highly recommend separating module power supply into two paths to maintain clean power as shown below for TX spurious performance. The VPH_PWR is for baseband and RF circuits. Layout Suggestion: 22F, 0.1uF, 12pF and 8pF capacitors must be placed as close to VCC pins as possible.
