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 measurement often is specified as
the ratio of the power spectral density (PSD) of the
CDMA main channel to the PSD measured at 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).
