(1) _{VCC1 = +3.5 V, VBIAS = +3.5 V, VREF = +2.85 V, Freq = 906 MHz, TC = +25 °C, unless otherwise specified.}
(2) _{For low power mode, VCC1 and VCC2 = 1.4 V}
(3) _{ACP is specified per CDMA2000 as the ratio of the total in-band power (1.23 MHz BW) to adjacent power in a 30 kHz BW.}
(4) _{CDMA2000 is configured as DCCH = 9600, SCHO = 9600, PCH (Walsh 0) = –3.75 dB, and Peak-to-Average Ratio (CCDF = 1%) = 4.5 dB.}
For IS95, PO = 27.5 dBm is acceptable to meet the specified ACPR values.
(5) _{All phases, time = 10 seconds.}
