Functional Diagram General Description
The HMC601LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC T voltage at its output. The HMC601LP4(E) employ 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 S - SM move into saturation one by one creating an accurate R approximation of the logarithm function. The output of O a series of square law detectors is summed, converted T into voltage domain and buffered to drive the LOGOUT C output. For detection mode, the LOGOUT pin is E shorted to the VSET input, and will provide a nominal T logarithmic slope of 19mV/dB and an intercept of E -100dBm. The HMC601LP4(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 The HMC601LP4(E) provides a 15/34ns (rise/fall time) E response time enabling RF burst detection to a pulse W rate beyond 20 MHz. O
