Power Working Domains
The working areas of the RF transmitter are divided into several domains as defined in
Figure 101
.
P
TYP
T
A
= 25 °C to 60 °C and V
DD
= 2.5 V to 3.6 V
P
TYP
is where the power step is adjusted to guarantee 5 dBm. The power consumption in this domain is specified at 5 dBm output
power step at nominal conditions of T
A
= 25 °C and V
DD
= 3 VDC.
P
MIN
P
MIN
is where the power step is adjusted to guarantee a minimum of 3 dBm as shown in
Figure 101
. The power consumption in
this domain is given as the maximum consumption at whatever temperature of supply voltage condition. The P
MIN
domain is
subdivided into two areas according to the lowest supply voltage encountered (1.8 or 2.5 VDC).
