What voltage is required for the Digi XBee SX 900 to transmit at its full 1 W power output?

[koffan]

The Digi XBee SX 900 datasheet specifies a 3.3 V supply voltage and states that the module can transmit at up to 1 W output power. However, the PL parameter description in XCTU indicates that a supply voltage of 5 V or higher is required to achieve the full 1 W output power.

Which specification is correct? Could you clarify the actual supply voltage requirement for achieving the maximum 1 W transmit power?

The message in XCTU is a bug in the document that pertains to the 9Xtend and not the SX. The XS is a 2.6 - 3.6V product.
