v1.19 DETECTOR / CONTROLLER, 5-8 MHz Power Detectors - SMT Typical Applications The is ideal for: Cellular Infrastructure WiMAX, WiBro & LTE/G Power Monitoring & Control Circuitry Receiver Signal Strength Indication (rssi) Automatic Gain & Power Control Military, ecm & Radar Functional Diagram Features Wide Dynamic Range: up to 5 db High Accuracy: ±1 db with 5 db Range Up To.7 GHz Fast Output Response Time Supply Voltage: +.7 to +5.5V Power-Down Mode Excellent Stability over Temperature 1 Lead 3x3 mm SMT Package: 9mm² General Description The Logarithmic Detector/Controller is ideal for converting the power of RF signals with frequencies in the 5 MHz to 8 MHz range, to a DC voltage, proportional to input power, at its output. The employs a successive compression technology which delivers 5 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 output. For detection mode, the pin is connected to the Vset input and will provide a nominal logarithmic slope of 17 mv/db and an intercept of 8 dbm. The 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.

Note : For detector mode, connect high impedance volt meter to the / port. Note 3: For controller mode, remove R9 & C3 and install 1k Ω resistor (R7, not included) and 1pF capacitor (C, not included), then make appropriate connection to and Vset. In controller mode, the / output can be used to drive a variable gain amplifier, or a variable attenuator, either directly or through a buffer or microcontroller. Vset should be connected to an external supply, typically between +. and +1.V.
