Range @ 2.1 V, +25°C: 7.5 dBm +/- 1 dBm

Typ. temperature dependency at 2.1 V: +0.2 dBm@-40°C and -0.6 dBm@+125°C, reference +25°C

Range @ 3.0 V, +25°C: 10.4 dBm +/- 2.0 dBm

Typ. temperature dependency at 3.0 V: -0.2 dBm@-40°C and -0.7 dBm@+125°C, reference +25°C.

Range @ 4.0 V, +25°C: 11.7 dBm +/- 2.5 dBm

Typ. temperature dependency at 4.0 V: -0.8 dBm@-40°C and -0.6 dBm@+125°C, reference +25°C.

Tolerances of the passive elements not taken into account.

A smaller load impedance reduces the supply-voltage dependency.

A higher load impedance reduces the temperature dependency.
