CC1110Fx / CC1111Fx

7.3 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.

Differential impedance as seen from the RF-port (RF_P and

RF_N) towards the antenna. Follow the CC1110EM

reference designs ([1], [2] and [3]) available from the TI

+10

dBm Output power is programmable, and full range is available in

all frequency bands

Output power may be restricted by regulatory limits. See

Application Note AN050 [13] – note that this AN is for CC1101

but the same limitations apply for CC1110Fx and CC1111Fx as

well. For CC1111Fx see in addition Design Note DN016 [14] for

information on antenna solution and additional regulatory

restrictions

See figure Figure 3 for typical variation over operating

conditions
