General Description
The HMC713MS8(E) Logarithmic Detector/Control-
ler is ideal for converting RF signals with frequencies
in the 100 MHz to 2700 MHz range, to a proportional
DC voltage at its output. The HMC713MS8(E) employs
a successive compression technology which delivers
54 dB of dynamic range with high conversion accuracy
over a wide input frequency range. As the input signal
is increased, successive amplifiers move into satura-
tion one by one creating an accurate approximation
of the logarithm function. The outputs of a series of
detectors are summed, converted into voltage domain
and buffered to drive the OUT output. For detection
mode, the OUT pin is connected to the VSET input and
will provide a nominal logarithmic slope of 17 mV/dB
and an intercept of -68 dBm. The HMC713MS8(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.
