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

website.

Output power,

highest setting

+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

The antennas used during the radiated measurements

(SMAFF-433 from R.W.Badland and Nearson

S331 868/915) play a part in attenuating the harmonics
