HMC600LP4E

HMC600LP4 / 600LP4E v02.0909 75 dB LOGARITHMIC DETECTOR / CONTROLLER 50 - 4000 MHz Typical Applications Features The HMC600LP4 / HMC600LP4E is ideal for IF and RF applications in: Wide Dynamic Range: up to 75 dB • Cellular/PCS/3G Power-Down Mode • WiMAX, WiBro & Fixed Wireless Excellent Stability over Temperature • Power Monitoring & Control Circuitry Compact 4x4mm Leadless SMT Package Flexible Supply Voltage: +2.7V to +5.5V • Receiver Signal Strength Indication (RSSI) • Automatic Gain & Power Control POWER DETECTORS - SMT 12 General Description Functional Diagram The HMC600LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC600LP4(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 19mV/dB and an intercept of -95 dBm. The HMC600LP4(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.

Note 2: For single-ended input operation, use the INP port and make no connection to INN. INN is AC coupled to ground by C2 Note 3: For differential input, remove C2, and install a 1000pF capacitor in series with INN at location shown. Note 4: For detector mode, connect high impedence volt meter to the LOGOUT port, and make no connection to VSET. LOGOUT is shorted to VSET by R3, as required for detector mode. Note 5: For controller mode, remove R3 and make appropriate connection to LOGOUT and VSET. In controller mode, the LOGOUT 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 +0.6 and +1.9V.
