MAX2016ETI-MAX2016ETI+D
2.7 V to 5.25 V, LF-to-2.5 GHz dual logarithmic detector/controller for power, gain, and VSWR measurement
General DescriptionThe MAX2016 dual logarithmic detector/controller is a
fully integrated system designed for measuring and
comparing power, gain/loss, and voltage standing-wave
ratio (VSWR) of two incoming RF signals. An internal
broadband impedance match on the two differential RF
input ports allows for the simultaneous monitoring of sig-
nals ranging from low frequency to 2.5GHz.
The MAX2016 uses a pair of logarithmic amplifiers to
detect and compare the power levels of two RF input
signals. The device internally subtracts one power level
from the other to provide a DC output voltage that is pro-
portional to the power difference (gain). The MAX2016
can also measure the return loss/VSWR of an RF signal
by monitoring the incident and reflected power levels
associated with any given load. A window detector is
easily implemented by using the on-chip comparators,
OR gate, and 2V reference. This combination of circuitry
provides an automatic indication of when the measured
gain is outside a programmable range. Alarm monitoring
can thus be implemented for detecting high-VSWR
states (such as open or shorted loads).
The MAX2016 operates from a single +2.7V to +5.25V*
power supply and is specified over the extended -40°C
to +85°C temperature range. The MAX2016 is available
in a space-saving, 5mm x 5mm, 28-pin thin QFN.

Note 3:Dynamic range refers to the range over which the error remains within the ±3dB range.
Note 4:The slope is the variation of the output voltage per change in input power. It is calculated by fitting a root-mean-square
straight line to the data indicated by the RF input power range.
Note 5:The intercept is an extrapolated value that corresponds to the output power for which the output voltage is zero. It is calcu-
lated by fitting a root-mean-square straight line to the data.

MAX2016
LF-to-2.5GHz Dual Logarithmic Detector/
Controller for Power, Gain, and VSWR Measurements
Detailed DescriptionThe MAX2016 dual logarithmic amplifier is designed for
a multitude of applications including dual-channel RF
power measurements, AGC control, gain/loss detection,
and VSWR monitoring. This device measures RF signals
ranging from low frequency to 2.5GHz, and operates
from a single 2.7V to 5.25V (using series resistor, R6)
power supply. As with its single-channel counterpart
(MAX2015), the MAX2016 provides unparalleled perfor-
mance with a high 80dB dynamic range at 100MHz and
exceptional accuracy over the extended temperature
and supply voltage ranges.
The MAX2016 uses a pair of logarithmic amplifiers to
detect and compare the power levels of two RF input
signals. The device subtracts one power level from the
other to provide a DC output voltage that is proportional
to the power difference (gain). The MAX2016 can also
measure the return loss/VSWR of an RF signal by moni-
toring the incident and reflected power levels associat-
ed with any given load.
A window detector is easily implemented by using the
on-chip comparators, OR gate, and 2V reference. This
combination of circuitry provides an automatic indica-
tion of when the measured gain is outside a program-
mable range. Alarm monitoring can thus be imple-
mented for detecting high-VSWR states (such as open
or shorted loads).
RF Inputs (RFINA and RFINB)The MAX2016 has two differential RF inputs. The input
to detector A (RFINA) uses the two input ports RFINA+
and RFINA-, and the input to detector B (RFINB) uses
the two input ports RFINB+ and RFINB-.
