Functional Diagram

General Description

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 micro-

wave radio and VSAT applications, the HMC662LP3E

is housed in a compact 3x3 mm RoHS compliant SMT

plastic package.
