Functional Diagram POWER DETECTORS -SMT General Description
The HMC611LP4(E) Logarithmic Detector/Controller
converts RF signals at its input, to a proportional DC
voltage at its output. The HMC611LP4(E) 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 -25mV/
dB and an intercept of 18 dBm (22 dBm for ƒ ≥ 5.8 GHz).
The HMC611LP4(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. Electrical Specifi cations, TA = +25C[1]
