General Description

The HMC612LP4(E) Logarithmic Detector/Controller is

ideal for converting input signals with frequencies in the

50 Hz to 3 GHz range, to a proportional DC voltage at

its output. The HMC612LP4(E) employs a successive

compression technology which delivers extremely high

dynamic range and conversion accuracy over a wide

input frequency range. As the input signal is increased,

successive amplifi ers move into saturation one by one

creating an accurate approximation of the logarithm

function. The output of a series of square law detectors

is summed, converted into voltage domain and buff-

ered to drive the LOGOUT output. For detection mode,

the LOGOUT pin is shorted to the VSET input and will

provide a nominal logarithmic slope of 19 mV/dB and an

intercept of -99 dBm. The HMC612LP4(E) can also be

used in the controller mode where an external voltage

is applied to the VSET pin, to create an AGC or APC

feedback loop.
