HMC611LP4E Datasheet PDF - ADI

The HMC611LP4E is a Logarithmic Detector/Controller that converts RF signals at its input, to a proportional DC voltage at its output. It employs a successive compression topology which delivers extremely high dynamic range and conversion accuracy over a wide input frequency range. As the input power is increased, successive amplifier moves into saturation one by one creating an accurate approximation of the logarithm function. The output of a series of square law detectors is summed, converted into voltage domain and buffered to drive the LOGOUT output. For detection mode, the LOGOUT pin is shorted to the VSET input and will provide a nominal logarithmic slope of -25mV/dB and an intercept of 18dBm (22dBm for ƒ >=5.8GHz). The HMC611LP4E 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.
