| HMC602LP4 / 602LP4E v01.0407 70 dB, LOGARITHMIC DETECTOR / CONTROLLER, 1 - 8000 MHz Typical Applications The HMC602LP4(E) is ideal for IF and RF applications in: * Cellular/PCS/3G * WiMAX, WiBro, WLAN, Fixed Wireless & Radar * Power Monitoring & Control Circuitry Features Wide Dynamic Range: up to 70 dB High Accuracy: 1 dB with 60 dB Range Up To 6 GHz Fast: 8ns Output Response Time Supply Voltage: +5V Power-Down Mode Excellent Stability over Temperature Buffered Temperature Sensor Output Compact 4x4mm Leadless SMT Package 8 POWER DETECTORS - SMT * Receiver Signal Strength Indication (RSSI) * Automatic Gain & Power Control Functional Diagram General Description The HMC602LP4(E) Logarithmic Detector/Controller converts RF signals at its input, to a proportional DC voltage at its output. The HMC602LP4(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 -25mV/ dB and an intercept of 12 dBm (19 dBm for 5.8 GHz). The HMC602LP4(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 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 0 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 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. Note 4: Terminal CPB must be connected to ground for proper operation. 8 - 30 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com HMC602LP4 / 602LP4E v01.0407 70 dB, LOGARITHMIC DETECTOR / CONTROLLER, 1 - 8000 MHz Evaluation PCB 8 POWER DETECTORS - SMT 8 - 31 List of Materials for Evaluation PCB 115402 [1] Item J1 - J3 J4 J5 - J11 C1, C2 C3, C5, C7 C4, C6, C8 C9 R1 R2 R3 R4 - R6, R9 R8, R12 U1 PCB [2] Description PC Mount SMA Connector Molex Connector Header DC Pin 1000 pF Capacitor, 0402 Pkg. 100 pF Capacitor, 0402 Pkg. 0.1F Capacitor, 0603 Pkg. 220 pF Capacitor, 0603 Pkg. 68 Resistor, 0603 Pkg. 1k Resistor, 0603 Pkg. 10k Resistor, 0603 Pkg. 0 Resistor, 0603 Pkg. 0 Resistor, 0402 Pkg.
