HMC602LP4

HMC602LP4 / 602LP4E v03.0209 70 dB, LOGARITHMIC DETECTOR / CONTROLLER, 1 - 8000 MHz POWER DETECTORS - SMT 12 12 - 18 Typical Applications The HMC602LP4(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 Functional Diagram Features Wide Dynamic Range: up to 70 dB High Accuracy: ±1 dB with 60 dB Range Up To 6 GHz Fast: 10ns Output Response Time Supply Voltage: +5V Power-Down Mode Excellent Stability over Temperature Buffered Temperature Sensor Output Compact 4x4mm Leadless SMT Package General Description The HMC602LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC602LP4(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 (23 dBm for ƒ > 5.8 GHz). The HMC602LP4(E) can also be used in the controller mode where an exte...
