MAX2015

0.1GHz to 3GHz, 75dB Logarithmic Detector/Controller

0.1GHz to 3GHz, 75dB RF Log Detector/Controller Delivers Best Dynamic Range and Precision Over Temperature


Please check latest availability status for a specific part variant.

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 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.
