1 _{Per Table 2 over dynamic range up to 28 dBm output power, unless otherwise specified}
2 _{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.}
3 _{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.
4 _{All phases, time = 10 seconds; VCC = 4.2 V; Freq. = 1850 MHz, 1880 MHz, 1910 MHz; TCASE = –30 °C, +25 °C, +85 °C; PO set using 50 Ω load, PIN held constant during mismatch.}
5 _{TONDC is time required to reach stable quiescent bias (±10%) after VREF is switched high.}
TOFFDC is time required for battery to decrease to < 100 µA after VREF is switched low.
After ICQ is stable, The TONRF is time to reach final output power (±1 dB) once RF input is applied.
TOFFRF is time required for PO to drop 30 dB once RF input is removed.
