Functional Diagram
General Description
The HMC611 Logarithmic Detector/Controller generates
a voltage that is proportional to the log of the RF power
envelop presented to its input. The HMC611 employs
a successive compression topology which delivers
extremely high dynamic range and conversion accuracy
over a wide input frequency range. As the input power
is increased, successive amplifiers 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 buffered 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 -25 mV/
dB and an intercept of 9 dBm (24 dBm for ƒ ≥ 5.8 GHz).
The HMC611 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.
