ACPR Measurement Method
Adjacent-channel power ratio
(ACPR) is used to characterize
the distortion of power amplifiers
and other subsystems for their
tendency to cause interference
with neighboring radio channels
or systems. The ACPR measure-
ment often is specified as the
ratio of the power spectral
density (PSD) of the CDMA main
channel to the PSD measured at
Figure 18. CDMA Adjacent-Channel Power Ratio Measurement.
several offset frequencies. For the
Cellular band (824 ~ 849 MHz
transmitter channel), the two
offsets are at
±
885 kHz and
±
1.98 MHz and the measurement
resolution bandwidth specified is
30 kHz. These offsets are at
±
1.25 MHz and
±
1.98 MHz for the
PCS band (1850 ~ 1910 MHz
transmitter channel).
