11.1 TX Power Characteristics
The diagrams below show the typical output power and module current in dependency on module
supply voltage and EM250 power setting in NORMAL MODE.
Please Note: The power setting is the setting of the EM250’s output power (before amplification). This setting is used by
all firmware running on the ETRX2-PA.
