Combinations of these channels will increase the peak
to average power ratio for higher data rates. The
complementary cumulative distribution function
(CCDF) measurement characterizes the peak to average
power statistics of CDMA2000 reverse link. For
reference, the system specifications of peak to average
power ratio of IS-95 and CDMA2000 IX RTT are 3.9 dB
and 5.4 dB at 1% CCDF respectively.

Higher peak to average power ratio requires a higher
margin, both in higher power gain and in improved
thermal stability for PA linearity to meet the minimum
system specifications.
The test results below for the ACPM-7833 show the
compliance to the system linearity specifications with
4 channel configurations, representing a broad cross-
section of CDMA2000 1X RTT environments.
