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

HMC600LP4 / HMC600LP4E Logarithmic Detector / Controller 115244 Evaluation PCB The circuit board used in the final application should use RF circuit design techniques. Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.

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.
