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.

AD8306-EVALZ is a fully populated, 4-layer, FR4-based, full featured evaluation board designed to allow easy evaluation of all features of the AD8306. RF input, limiter output and VLOG output SMA connections with single ended setups are featured. There is an option of full differential signaling on the RF input and limiter output at card edge if the user desires. Access to the +5V/16 mA supply is achieved with clip leads to the Vs and COM testpoints; it has a range from +2.7 to +6.5V.
