Per Table 2, 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)
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 CDMA2000, 0.5 dB back-off in output power is
required.

(5)
Worst case ACPR is –43dBc at +85 °C, VCC = 3.2 V.
All phases, time = 10 seconds.
