CC1110Fx / CC1111Fx
6.3 RF Transmit Section
TA = 25 C, VDD = 3.0 V if nothing else stated. All measurement results are obtained using the
CC1110EM reference designs ([1]) if nothing else is stated.

dBm Output power is programmable, and full range is available in
all frequency bands
Output power may be restricted by regulatory limits. See
AN050 [13]. Note that this application note is for CC1101 but the
same limitations apply to CC1110Fx and CC1111Fx as well. For
CC1111Fx see in addition DN016 [14] for information on antenna
solution and additional regulatory restrictions
