Figure 19. Setup for Single-Ended Data
Use as a Detector
The ADL5391 can be used as a square law detector. When
amplitude squaring is performed, there are components of the
multiplier output that correlate to the signal bleedthrough and
second harmonic, as seen in Equation 4. However, as noted in
the
Squaring and Frequency Doubling section, there is also a dc
component that is directly related to the offset and the squared
input magnitude. If a signal is split and feed into the X and Y
inputs and a low-pass filter were place on the output, the resulting
dc signal would be directly related to the square of the input
magnitude. The intercept of the response will shift slightly from
part to part (and over temperature) with the offset, but this can
be removed through calibration.
Figure 20 shows the response
of the ADL5391 as a square law detector,
Figure 21 shows the
error vs. the input power, and
Figure 22 shows the
configuration used.

SMA connectors for single-ended, high frequency operation. If J5
and J6 are used, R9, R10, R14, and R15 should be removed. R2 and
R3 should also be populated to match the inputs. If used in broadband
operation, C4, C7, C8, and C2 need to be replaced with 0 Ω resistors.
WP, ZP, YP, XP
J2, J4, J7, J9
SMA connectors for broadband differential operation. If these are
used, baluns should be removed and jumped over using 0 Ω
resistors, and C14, C15, C18, and C20 should be removed.
