HMC713LP3E

HMC713LP3E v00.0909 54 dB, LOGARITHMIC DETECTOR / CONTROLLER, 50 - 8000 MHz Typical Applications The HMC713LP3E is ideal for: Cellular Infrastructure WiMAX, WiBro & LTE/4G Power Monitoring & Control Circuitry Receiver Signal Strength Indication (RSSI) Automatic Gain & Power Control Military, ECM & Radar Features Wide Dynamic Range: up to 54 dB High Accuracy: ±1 dB with 54 dB Range Up To 2.7 GHz Fast Output Response Time Supply Voltage: +2.7 to +5.5V Power-Down Mode Excellent Stability over Temperature 16 Lead 3x3 mm SMT Package: 9mm2 12 Functional Diagram General Description The HMC713LP3E Logarithmic Detector/Controller is ideal for converting the power of RF signals with frequencies in the 50 MHz to 8000 MHz range, to a DC voltage, proportional to input power, at its output. The HMC713LP3E employs a successive compression technology which delivers 54 dB of dynamic range with high measurement 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 outputs of a series of detectors are summed, converted into voltage domain and buffered to drive the OUTP output. For detection mode, the OUTP pin is connected to the VSET input and will provide a nominal logarithmic slope of 17 mV/dB  and an intercept of -68 dBm. The HMC713LP3E can also be used in the controller mode where an external voltage is applied to the VSET pin to cr...
