0.1GHz to 2.5GHz, 75dB Logarithmic

Detector/Controller

General Description

Features

The MAX2015 complete multistage logarithmic amplifier

is designed to accurately convert radio-frequency (RF)

signal power in the 0.1GHz to 2.5GHz 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.

ꢀ Complete RF Detector/Controller

ꢀ 0.1GHz to 2.5GHz Frequency Range

ꢀ Exceptional Accuracy Over Temperature

ꢀ High Dynamic Range

ꢀ 2.7V to 5.25V Supply Voltage Range*

ꢀ Scaling Stable Over Supply and Temperature

Variations

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.

ꢀ Controller Mode with Error Output

ꢀ Shutdown Mode with Typically 1µA of Supply

Current

ꢀ Available in 8-Pin µMAX Package

*See Power-Supply Connections section.

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.
