HMC612LP4 / 612LP4E v01.0108 75 dB LOGARITHMIC DETECTOR / CONTROLLER, 50 Hz - 3000 MHz POWER DETECTORS - SMT 7 Typical Applications Features The HMC612LP4(E) is ideal for IF and RF applications in: Wide Input Bandwidth: 50 Hz to 3 GHz • 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 • Automatic Gain & Power Control Compact 4x4mm Leadless SMT Package Functional Diagram General Description Wide Dynamic Range: Up to 74 dB 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 amplifiers 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 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 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.
