AD8306 5 MHz TO 400 MHz, 100 dB High Precision Limiting - Logarithmic Amplifier

The AD8306 is a complete IF limiting amplifier, providing both an accurate logarithmic (decibel) measure of the input signal (the RSSI function) over a dynamic range of 100 dB, and a programmable limiter output, useful from 5 MHz to 400 MHz.

An evaluation board is available for this product and may be ordered using the following product number: AD8306-EVAL. Schematic and layout for this evaluation board is contained in the product datasheet.
