HMC601LP4 / 601LP4E
General Description
Features
Functional Diagram
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 ampli 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 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
rate beyond 20 MHz.
Wide Dynamic Range: up to 75 dB
Fast Pulse Response: 15/34ns (Rise/Fall Time)
Flexible Supply Voltage: +2.7V to +5.5V
Power-Down Mode
Excellent Stability over Temperature
Compact 4x4mm Leadless SMT Package
Typical Applications
The HMC601LP4(E) 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 Circuits

Evaluation PCB
The circuit board used in the nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected 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.

Notes
Note 1: The HMC601LP4 & HMC601LP4E evaluation boards are pre-assembled for single-ended input, and detector/RSSI mode.
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 ampli er, 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.
