Product Summary
The AD8313ARMZ is a complete multistage demodulating logarithmic amplifier that can accurately convert an RF signal at its differ-ential input to an equivalent decibel-scaled value at its dc output. The AD8313ARMZ maintains a high degree of log conformance for signal frequencies from 0.1 GHz to 2.5 GHz and is useful over the range of 10 MHz to 3.5 GHz. The applications of the AD8313ARMZ include RF transmitter power amplifier setpoint control and level monitoring, Logarithmic amplifier for RSSI measurement cellular base stations, radio link, radar.
