2.6 Transmit Power Back-off
When 2.7 V < VBAT < 3.6 V, the output power shall be backed off by 0.8 dB per300 mV drop of Vbat
below 3.6 V to guarantee meeting spectral mask, EVM, harmoniclevels, spurious emissions and
regulatory requirements in general.
When 2.3 V < VBAT < 2.7 V, an additional back-off of the output power is needed to guarantee
meeting spectral mask, EVM, harmonic levels, spurious emissions and regulatory requirements in
general.
When the load is not 50Ω, the output power is backed off to guarantee meeting spectral mask, EVM,
harmonic levels, spurious emissions and regulatory requirements in general. The device is able to
withstand a VSWR of up to 12:1 without any damage.
When the temperature increases from +25°C to +85°C, the output power shall be backed off by 0.25
dB per 10°C increase to guarantee meeting spectral mask, EVM, harmonic levels, spurious
emissions and regulatory requirements in general.
