All figures below are indicative and typical, and are not a specification. These figures only highlight behavior of thePA over voltage and current.Figures for the SX1262 are given with DC-DC regulation enabled, which applies only to the circuit core.On the SX1262, the PA is optimized for maximum output power whilst maximizing the efficiency, which makes itmandatory to supply the power amplifier with fairly high voltages to maintain an high output power. To summarize:• the current efficiency of the PA is optimal at the highest output power step• output power will be limited by the voltage supplied to VBAT.This is illustrated in the following figure:
