MAX2014EUA+T

P1-P3P4-P6P7-P9P10-P12
General Description
The MAX2014 complete multistage logarithmic amplifier is
designed to accurately convert radio-frequency (RF) sig-
nal power in the 50MHz to 1000MHz 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 MAX2014 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.
Applications
AGC Measurement and Control
RF Transmitter Power Measurement
RSSI Measurements
Cellular Base-Station, WLAN, Microwave Link,
Radar, and other Military Applications
