ADL5501
APPLICATIONS
BASIC CONNECTIONS
Figure 40 shows the basic connections for the ADL5501. The
device is powered by a single supply of between 2.7 V and 5.5 V,
with a quiescent current of 1.1 mA. The VPOS pin is decoupled
using 100 pF and 0.1 μF capacitors.

The ADL5501 RF input does not require external termination
components because it is internally matched for an overall
broadband input impedance of 50 Ω.

OUTPUT SWING
At 900 MHz, the output voltage is nominally 6.3 times the input
rms voltage (a conversion gain of 6.3 V/V rms). The output voltage
swings from near ground to 4.9 V on a 5.0 V supply.
Figure 41 shows the output swing of the ADL5501 to a CW input
for various supply voltages. It is clear from Figure 41 that
operating the device at lower supply voltages reduces the
dynamic range as the output headroom decreases.

LINEARITY
Because the ADL5501 is a linear-responding device, plots of
output voltage vs. input voltage result in a straight line. It is more
useful to plot the error on a logarithmic scale, as shown in
Figure 42. The deviation of the plot for the ideal straight-line
characteristic is caused by output clipping at the high end and
by signal offsets at the low end. However, it should be noted that
offsets at the low end can be either positive or negative; therefore,
this plot could also trend upwards at the low end. Figure 10
through Figure 12 and Figure 16 through Figure 18 show error
distributions for a large population of devices at specific
frequencies.

It is also apparent in Figure 42 that the error plot tends to shift
to the right with increasing frequency. The squaring cell has an
input impedance that decreases with frequency. The matching
network compensates for the change and maintains the input
impedance at a nominal 50 Ω. The result is a decrease in the
actual voltage across the squaring cell as the frequency increases,
reducing the conversion gain. Similarly, conversion gain is less
at frequencies near 100 MHz because of the small on-chip
coupling capacitor.
