General Description
POWER DETECTORS - SMT
12
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 amplifiers move into
saturation one by one creating an approximation of
the logarithm function. The output of a series of square
law 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 microwave radio and VSAT applications, the HMC662LP3E
is housed in a compact 3x3 mm RoHS compliant SMT
plastic package.

The circuit board used in the final 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.
