HMC6357MS8GE
v00.1011 54 dB, LOGARITHMIC
DETECTOR / CONTROLLER, 100 - 2700 MHz
General Description
Features
Functional Diagram
The HMC6357MS8GE Logarithmic Detector/Control-
ler is ideal for converting RF signals with frequencies
in the 100 MHz to 2700 MHz range, to a proportional
DC voltage at its output. The HMC6357MS8GE em-
ploys a successive compression technology which
delivers 54 dB of dynamic range with high conversion
accuracy over a wide input frequency range. As the in-
put signal is increased, successive ampli ers move into
saturation one by one creating an accurate approxima-
tion of the logarithm function. The outputs of a series of
detectors are summed, converted into voltage domain
and buffered to drive the OUT output. For detection
mode, the OUT pin is connected to the VSET input and
will provide a nominal logarithmic slope of 17.2 mV/dB
and an intercept of -68 dBm. The HMC6357MS8GE
can also be used in the controller mode where an ex-
ternal voltage is applied to the VSET pin to create an
AGC or APC feedback loop.
Wide Dynamic Range: up to 54 dB
High Accuracy:
±1 dB with 54 dB Range Up To 2.7 GHz
Fast Output Response Time
Supply Voltage: +2.7 to +5.5V
Power-Down Mode
Excellent Stability over Temperature
MSOP-8 SMT Package: 14.8 mm
Typical Applications

Notes
Note 1: The HMC6357MS8GE evaluation board is pre-assembled for single-ended input, and detector/RSSI mode.
Note 2: For detector mode, connect high impedance volt meter to the OUT port.
Note 3: For controller mode, remove R6 & C3 and install 1k Ω resistor (R4) and 100pF capacitor (C2), then make appropriate
connection to OUT and VSET. In controller mode, the OUT 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 +0.2 and +1.2V.
Note 4: An external capacitance C1 can be connected to CLPF port for additional  ltering of OUT outputs..

Evaluation PCB
The circuit board used in the 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.
