HMC601LP4 / 601LP4E
v01.0509 75 dB, FAST SETTLING, LOGARITHMIC
DETECTOR / CONTROLLER 10 -4000 MHz Typical Applications Features The HMC601LP4(E) is ideal for IF and RF
applications in: Wide Dynamic Range: up to 75 dB • Cellular/PCS/3G Flexible Supply Voltage: +2.7V to +5.5V • WiMAX, WiBro & Fixed Wireless Power-Down Mode • Power Monitoring & Control Circuitry Excellent Stability over Temperature • Receiver Signal Strength Indication (RSSI) Compact 4x4mm Leadless SMT Package Fast Pulse Response: 15/34ns (Rise/Fall Time) • Automatic Gain & Power Control Circuits POWER DETECTORS -SMT 12 Functional Diagram General Description
The HMC601LP4(E) Logarithmic Detector/Controller
converts RF signals at its input, to a proportional DC
voltage at its output. The HMC601LP4(E) employ
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
-100dBm. The HMC601LP4(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.
The HMC601LP4(E) provides a 15/34ns (rise/fall time)
response time enabling RF burst detection to a pulse …
