21.1

Shaping and PA Ramping

With ASK modulation, up to eight power

settings are used for shaping. The modulator

contains a counter that counts up when

transmitting a one and down when transmitting

a zero. The counter counts at a rate equal to 8

times the symbol rate. The counter saturates

at FREND0.PA_POWER and 0 respectively.

This counter value is used as an index for a

lookup in the power table. Thus, in order to

utilize the whole table, FREND0.PA_POWER

should be 7 when ASK is active. The shaping

of the ASK signal is dependent on the

configuration of the PATABLE. Figure 22

shows some examples of ASK shaping. Note

that the OOK/ASK pulse shaping feature on

the

CC1150 is only supported for output power

levels below -1 dBm.
