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.
