LF-to-2.5GHz Dual Logarithmic Detector/
Controller for Power, Gain, and VSWR Measurements
General Description
The 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.
