Figure 19. Basic Connections for Operation in Measurement Mode
CONTROLLER MODE
In addition to being a measurement device, the ADL5519 can
also be configured to measure and control signal levels. The
ADL5519 has two controller modes. Each of the two log
detectors can be separately configured to set and control the
output power level of a variable gain amplifier (VGA) or
variable voltage attenuator (VVA). Alternatively, the two log
detectors can be configured to measure and control the
gain
of
an amplifier or signal chain.
The channel difference outputs can be used for controlling a
feedback loop to the ADL5519’s RF inputs. A capacitor connected
between FBKA and OUTP forms an integrator, keeping in mind
that the on-chip 1 kΩ feedback resistor forms a zero. (The value
of the on-chip resistors can vary as much as ±20% with manufac-
turing process variation.) If Channel A is driven and Channel B
has a feedback loop from OUTP through a PA, then OUTP
integrates to a voltage value such that
OUTB
= (
OUTA
+
VLVL
)/2
(11)
The output value from OUTN may or may not be useful. It is
given by
OUTN
= 0 V
(12)
For VLVL < OUTA/3,
Otherwise,
OUTN
= (3 ×
VLVL
–
OUTA
)/2
(13)
If VLVL is connected to OUTA, then OUTB is forced to equal
OUTA through the feedback loop. This flexibility provides the
user with the capability to measure one channel operating at a
given power level and frequency while forcing the other channel
to a desired power level at another frequency. ADJA and ADJB
should be set to different voltage levels to reduce the temperature
drift of the output measurement. The temperature drift will be
statistical sum of the drift from Channel A and Channel B. As
stated before, VLVL can be used to force the slaved channel to
operate at a different power than the other channel. If the two
channels are forced to operate at different power levels, then
some static offset occurs due to voltage drops across metal
wiring in the IC.
If an inversion is necessary in the feedback loop, OUTN can be
used as the integrator by placing a capacitor between OUTN
