HMC601LP4 / 601LP4E v01.0509 75 dB, FAST SETTLING, LOGARITHMIC DETECTOR / CONTROLLER 10 - 4000 MHz Typical Applications Features The HMC601LP4(E) is ideal for IF and RF Wide Dynamic Range: up to 75 dB applications in: Fast Pulse Response: 15/34ns (Rise/Fall Time) Cellular/PCS/3G Flexible Supply Voltage: +2.7V to +5.5V WiMAX, WiBro & Fixed Wireless Power-Down Mode Power Monitoring & Control Circuitry Excellent Stability over Temperature Receiver Signal Strength Indication (RSSI) Compact 4x4mm Leadless SMT Package Automatic Gain & Power Control Circuits Functional Diagram General Description 12 The HMC601LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC601LP4(E) employ 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 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 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 -100dBm. The HMC601LP4(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. The HMC601LP4(E) provides a 15/34ns (rise/fall time) response time enabling RF burst detection to a pulse rate beyond 20 MHz. 1 Electrical Specifi cations, T = +25C, PWD = 0V, Vcc1, Vcc2 = +3.3V A Parameter Typ.
