HMC662LP3E
v05.0914
54 dB, LOGARITHMIC
DETECTOR, 8 - 30 GHz
The HMC662LP3E Logarithmic Detector converts
RF signals at its input, to a proportional DC voltage
at its output. The HMC662LP3E employs successive
compression topology which delivers high dynamic
range over a wide input frequency range. As the input
power is increased, successive ampliers move into
saturation one by one creating an approximation of
the logarithm function. The output of a series of
detectors is summed, converted into the voltage
domain and buffered to drive the LOG OUT output.
The HMC662LP3E provides a nominal logarithmic
slope of +13 mV/dB and an intercept of -127 dBm at
18 GHz. Ideal as a log detector for high volume micro-
wave radio and VSAT applications, the HMC662LP3E
is housed in a compact 3x3 mm RoHS compliant SMT
plastic package.

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 connected 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.
