1 v3.9 HMC6LP / 6LPE 7 db, LOGARITHMIC DETECTOR / CONTROLLER, 1-8 MHz 1 Typical Applications The HMC6LP(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 7 db High Accuracy: ±1 db with 6 db Range Up To 6 GHz Fast: 1ns Output Response Time Supply Voltage: +5V Power-Down Mode Excellent Stability over Temperature Buffered Temperature Sensor Output Compact xmm Leadless SMT Package General Description The HMC6LP(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC6LP(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 amplifi ers 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 -5mV/ db and an intercept of 18 dbm (3 dbm for ƒ > 5.8 GHz). The HMC6LP(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.

Package Base GND Exposed paddle must be connected to RF and DC ground. 1 Application & Evaluation PCB Schematic Notes Note 1: The HMC6LP & HMC6LPE evaluation boards are pre-assembled for single-ended input, and detector/rssi mode. Note : For detector mode, connect high impedance volt meter to the LOGOUT port, and make no connection to VSET. LOGOUT is shorted to VSET by R9, as required for detector mode. Note 3: For controller mode, remove R9 and install ohm resistor (R11), then make appropriate connection to LOGOUT and VSET. In controller mode, the LOGOUT output can be used to drive a variable gain amplifi er, or a variable attenuator, either directly or through a buffer or microcontroller. VSET should be connected to an external supply, typically between +.6 and +1.9V. 1 - Alpha Road, Chelmsford, MA 18 Phone: Fax:
