HMC611LP4E

HMC611LP4 / 611LP4E v04.0309 60 dB, LOGARITHMIC DETECTOR / CONTROLLER, 1 - 10000 MHz POWER DETECTORS - SMT 12 Typical Applications The HMC611LP4(E) is ideal for IF and RF applications in: Cellular/PCS/3G WiMAX, WiBro, WLAN, Fixed Wireless & Radar Power Monitoring & Control Circuitry Receiver Signal Strength Indication (RSSI) Automatic Gain & Power Control Features Wide Dynamic Range: Up to 63 dB High Accuracy: ±1 dB with 54 dB Range Up to 8 GHz Supply Voltage: +5V Excellent Stability over Temperature Buffered Temperature Sensor Output 24 Lead 4x4mm SMT Package: 16mm2 Functional Diagram General Description The HMC611LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC611LP4(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 -25mV/ dB and an intercept of 18 dBm (22 dBm for ƒ ≥ 5.8 GHz). The HMC611LP4(E) can also be used in the controller mode where an external voltage is applied to the VSET pin, to create an A...
