GENERAL DESCRIPTION
The AD8313 is a complete multistage demodulating logarithmic amplifier that can accurately convert an RF signal at its input to an equivalent decibel-scaled value at its dc output. The AD8313 maintains a high degree of log conformance for signal frequencies from 0.1 GH- to 2.5 GHz. Application is straightforward, requiring only a single supply of 2..
