Per Table 2 over dynamic range up to 28 dBm output power, unless otherwise specified
ACP is specified per IS95 as the ratio of the total in-band power (1.23 MHz BW) to adjacent power in a 30 kHz BW.
For CDMA2000 test configured as [PCH @ –3.75 dB, DCCH–9600 bps @ 0 dB; SCHO–9600 bps @ 0 dB] and other test configurations that yield a peak-to-average up to 4.5 dB for
CCDF = 1%, up to 1. dB power back off from the maximum listed for IS95 may be required to meet specified maximum ACP performance under worst-case conditions.
All phases, time = 10 seconds.
T
ON
DC is time required to reach stable quiescent bias (±10%) after V
REF
is switched high.
T
OFF
DC is time required for battery to decrease to < 100 µA after V
REF
is switched low.
After I
CQ
is stable, the T
ON
RF is time to reach final output power (±1 dB) once RF input is applied.
