The HMC611LP4(E) employs a successive compression topology which delivers S - SM extremely high dynamic range and conversion accuracy R over a wide input frequency range. As the input power O is increased, successive amplifi ers move into saturation T one by one creating an accurate approximation of the C logarithm function. The output of a series of square law E T detectors is summed, converted into voltage domain E 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/ R D dB and an intercept of 18 dBm (22 dBm for ƒ ≥ 5.8 GHz). E The HMC611LP4(E) can also be used in the controller W mode where an external voltage is applied to the VSET O pin, to create an AGC or APC feedback loop.
