ADL5390
3GPP2 C.S0010-B, Table 6.5.2.1) was applied to the ADL5390.
A cavity-tuned filter was used to reduce noise from the signal
source being applied to the device. The 4.6 MHz pass band of
this filter is apparent in the subsequent spectral plots.

Holding the I and Q gain control voltages steady at 0.353 V,
input power was swept. Figure 36 shows the resulting output
power, noise floor, and adjacent channel power ratio. The noise
floor is presented as noise in a 1 MHz bandwidth as defined by
the 3GPP2 specification.

ACP is still in compliance with the standard (<45 dBc @
750 kHz and <60 dBc @ 1.98 MHz) even with output powers
greater than +3 dBm. At low output power levels, ACP at
1.98 MHz carrier offset degrades as the noise floor of the
ADL5390 becomes the dominant contributor to measured ACP.
Measured noise at 4 MHz carrier offset begins to increase
sharply above 2 dBm output power. This increase is not due to
noise, but results from increased carrier-induced distortion. As
output power drops below 2 dBm, the noise floor drops towards
90 dBm.
With a fixed input power of 2.16 dBm, the output power was
again swept by changing V
IBB
and V
QBB
from 0 V to 500 mV.
The resulting output power, ACP, and noise floor are shown in
Figure 37.

In contrast to Figure 36, Figure 37 shows that for a fixed input
power, ACP remains fairly constant as gain and phase are
changed (this is not true for very high RF input powers) until
the noise floor of the ADL5390 becomes the dominant con-
tributor to the measured ACP.
