General Description Functional Diagram
The HMC600LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC T voltage at its output. The HMC600LP4(E) employs a successive compression topology which delivers extremely high dynamic range and conversion accuracy over a wide input frequency range. As the input power S - SM is increased, successive amplifi ers move into saturation R one by one creating an accurate approximation of the O logarithm function. The output of a series of square law T detectors is summed, converted into voltage domain C and buffered to drive the LOGOUT output. For detection E mode, the LOGOUT pin is shorted to the VSET input, T and will provide a nominal logarithmic slope of 19mV/dB E and an intercept of -95 dBm. The HMC600LP4(E) can also be used in the controller mode where an external R D voltage is applied to the VSET pin, to create an AGC or E APC feedback loop. W O
