1 / 10 page 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.
