MAX2015EUA
0.1GHz to 3GHz, 75dB Logarithmic Detector/Controller
General DescriptionThe MAX2015 complete multistage logarithmic amplifier
is designed to accurately convert radio-frequency (RF)
signal power in the 0.1GHz to 3GHz frequency range to
an equivalent DC voltage. The outstanding dynamic
range and precision over temperature of this log ampli-
fier make it particularly useful for a variety of base sta-
tion and other wireless applications, including
automatic gain control (AGC), transmitter power mea-
surements, and received signal strength indication
(RSSI) for terminal devices.
The MAX2015 can also be operated in a controller
mode where it measures, compares, and controls the
output power of a variable-gain amplifier as part of a
fully integrated AGC loop.
This logarithmic amplifier provides much wider mea-
surement range and superior accuracy compared to
controllers based on diode detectors, while achieving
excellent temperature stability over the full -40°C to
+85°C operating range.
ApplicationsAGC Measurement and Control
RF Transmitter Power Measurement

Radar, and other Military Applications

Note 1:The MAX2015 is guaranteed by design for TA= -40°C to +85°C, as specified.
Note 2:Typical minimum and maximum range of the detector at the stated frequency.
Note 3:Dynamic range refers to the range over which the error remains within the stated bounds. The error is calculated at -40°C
and +85°C, relative to the curve at +25°C.
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
(RMS) straight line to the data indicated by 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 calculated by fitting an RMS straight line to the data.
