HMC612LP4 / 612LP4E v01.0108 75 dB LOGARITHMIC DETECTOR / CONTROLLER, 50 Hz - 3000 MHz Typical Applications Features The HMC612LP4(E) is ideal for IF and RF applica- Wide Input Bandwidth: 50 Hz to 3 GHz tions in: Wide Dynamic Range: Up to 74 dB Cellular/PCS/3G High Accuracy: 1 dB with 60 dB Range Up to 0.9 GHz WiMAX, WiBro, WLAN, Fixed Wireless & Radar Supply Voltage: +2.7V to +5.5V Power Monitoring & Control Circuitry Excellent Stability over Temperature Receiver Signal Strength Indication (RSSI) Power-Down Mode 7 Automatic Gain & Power Control Compact 4x4mm Leadless SMT Package Functional Diagram General Description The HMC612LP4(E) Logarithmic Detector/Controller is ideal for converting input signals with frequencies in the 50 Hz to 3 GHz range, to a proportional DC voltage at its output. The HMC612LP4(E) employs a successive compression technology which delivers extremely high dynamic range and conversion accuracy over a wide input frequency range. As the input signal is increased, successive ampl ifiers move 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 buff- ered 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 19 mV/dB and an intercept of -99 dBm. The HMC612LP4(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. 1 Electrical Specifi cations, T = +25C A Parameter Typ.
