VSWR

(1)

Per Table 2, 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.
