HMC600LP4

HMC600LP4 / 600LP4E v02.0909 75 dB LOGARITHMIC DETECTOR / CONTROLLER 50 - 4000 MHz POWER DETECTORS - SMT 12 12 - 2 Typical Applications The HMC600LP4 / HMC600LP4E is ideal for IF and RF applications in: Cellular/PCS/3G WiMAX, WiBro & Fixed Wireless Power Monitoring & Control Circuitry Receiver Signal Strength Indication (RSSI) Automatic Gain & Power Control Functional Diagram Features Wide Dynamic Range: up to 75 dB Flexible Supply Voltage: +2.7V to +5.5V Power-Down Mode Excellent Stability over Temperature Compact 4x4mm Leadless SMT Package General Description The HMC600LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC600LP4(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 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 19mV/dB and an intercept of -95 dBm. The HMC600LP4(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. Electrical Specifications, TA = +25C, PWD = 0V,...
