HMC713MS8E (ANALOG DEVICES)

The HMC713MS8E is a 54dB Logarithmic Detector/Controller is ideal for converting RF signals with frequencies in the 45 to 2700MHz range, to a proportional DC voltage at its output. The HMC713MS8(E) employs a successive compression technology which delivers 54dB of dynamic range with high conversion accuracy over a wide input frequency range. As the input signal is increased, successive amplifiers move into saturation one by one creating an accurate approximation of the logarithm function. The outputs of a series of detectors are summed, converted into voltage domain and buffered to drive the OUT output. For detection mode, the OUT pin is connected to the VSET input and will provide a nominal logarithmic slope of 17mV/dB and an intercept of -68dBm. The HMC713MS8(E) can also be used in the controller mode where an external voltage is applied to the VSET pin to create an AGC or APC feedback loop.
