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 amplifier
make it particularly useful for a variety of base station
and other wireless applications, including
automatic gain control (AGC), transmitter power measurements,
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 measurement
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.
