0.1GHz to 3GHz, 75dB Logarithmic
Detector/Controller
General Description
The 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.
