The HMC611LP4(E) Logarithmic Detector/Controller
converts RF signals at its input, to a proportional DC
voltage at its output. The HMC611LP4(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 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 -25mV/
dB and an intercept of 18 dBm (22 dBm for ƒ ≥ 5.8 GHz).
The HMC611LP4(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.

Application & Evaluation PCB Schematic
Notes
Note 1: The HMC611LP4 & HMC611LP4E evaluation boards are pre-assembled for single-ended input, and detector/RSSI mode.
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 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.

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.
