The AD8318 is a demodulating logarithmic amplifier, capable of accurately converting an RF input to a corresponding decibel-scaled output voltage. It employs the progressive compression over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The device is used in measurement or controller mode. The AD8318 maintains accurate log conformance for of 1 MHz to 6 GHz and provides useful to 8 GHz. The input range is typically 60 dB (re: 50 ?) with error less than ±1 dB. The AD8318 has a 10 ns response time that enables RF burst detection to 45 MHz. The device provides unprece-dented logarithmic intercept stability vs. ambient temperature conditions. A 2 mV/°C slope temperature sensor output is also provided for additional system monitoring. A single supply of 5 V is required. Current consumption is typically 68 mA. Power consumption decreases to The AD8318 can be configured to provide a control voltage to a VGA, such as a power amplifier or a measurement output, from Pin VOUT. Because the output can be used for controller applications, wideband noise is minimal.

It worked for me. It was not packed very well and came without documentation.
