Functional Diagram General Description
The HMC602LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC T voltage at its output. The HMC602LP4(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 is increased, successive amplifi ers move into saturation S - SM one by one creating an accurate approximation of the R logarithm function. The output of a series of square law O detectors is summed, converted into voltage domain T and buffered to drive the LOGOUT output. For detection C mode, the LOGOUT pin is shorted to the VSET input, E and will provide a nominal logarithmic slope of -25mV/ T dB and an intercept of 18 dBm (23 dBm for ƒ > 5.8 GHz). E The HMC602LP4(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. R D E
