Description
The AD8318ACPZ is a demodulating logarithmic amplifier used for accurately converting an RF input signal to a corresponding decibel-scaled output voltage. The device employs the progressive compression technique over a cascaded amplifier chain, each stage of which is equipped with a detector cell. The AD8318 is used in measurement or controller mode, and it maintains accurate log conformance for signals of 1 MHz to 6 GHz and provides useful operation to 8 GHz. The input range is typically 60 dB (referenced to 50 Ω) with an error less than ±1 dB. The device provides unprecedented logarithmic intercept stability vs. ambient temperature conditions and has a 10 ns response time that enables RF burst detection to beyond 45 MHz.
