The HMC713LP3E is a 54dB Logarithmic Detector/Controller, ideal for converting the power of RF signals with frequencies in the 50 to 8000MHz range, to a DC voltage, proportional to input power, at its output. The HMC713LP3E employs a successive compression technology which delivers 54dB of dynamic range with high measurement 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 OUTP output. For detection mode, the OUTP pin is connected to the VSET input and will provide a nominal logarithmic slope of 17mV/dB and an intercept of -68dBm. The HMC713LP3E 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.
