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. Electrical Specifi cations, TA = +25C, PWD = 0V, Vcc1, Vcc2 = +3.3V [1]
