General Description
The HMC713LP3E Logarithmic Detector/Controller is
ideal for converting the power of RF signals with fre-
quencies in the 50 MHz to 8000 MHz range, to a DC
voltage, proportional to input power, at its output. The
HMC713LP3E employs a successive compression
technology which delivers 54 dB of dynamic range with
high measurement accuracy over a wide input frequen-
cy range. As the input signal is increased, successive
amplifiers move into saturation one by one creating an
accurate approximation of the logarithm function. The
outputs of a series of detectors are summed, convert-
ed into voltage domain and buffered to drive the OUTP
output.
For detection mode, the OUTP 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
HMC713LP3E 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.
