Figure 15. Gain and Noise Figure vs. Frequency.
Input and output return loss are both greater that
10 dB. Although somewhat narrowband, the response
is adequate in the frequency range of 2110 MHz to
2170 MHz for the WCDMA downlink. If wider band
response is need, using a balanced configuration
improves return loss and doubles OIP3.

Perhaps the most critical system level specification for
the ATF521P8 lies in its distortionless output power.
Typically, amplifiers are characterized for linearity by
measuring OIP3. This is a twotone harmonic mea
surement using CW signals. But because WCDMA is
a modulated waveform spread across 3.84 MHz, it is
difficult to correlated good OIP3 to good ACLR. Thus,
both are measured and presented to avoid ambiguity.
