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 specifica-
tions 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-7813 show the compliance
to the system linearity specifica-
tions with 4 channel configura-
tions, representing a broad
cross-section of CDMA2000 1X
RTT environments.
Test result of ACPM-7813 using CDMA2000 1X RTT signal
Test condition - PA Evaluation board with Vdd1=Vdd2=Vbias = 3.4V, Vcntl = 2.5V, Frequency = 836 MHz. Test result with each channel configuration.
