AD606JCHIPS

a 50 MHz, 80 dB Demodulating Logarithmic Amplifier with Limiter Output AD606 a loadable output voltage of +0.1 V dc to +4 V dc. The logarithmic scaling is such that the output is +0.5 V for a sinusoidal input of –75 dBm and +3.5 V at an input of +5 dBm; over this range the logarithmic linearity is typically within ± 0.4 dB. All scaling parameters are proportional to the supply voltage.
