Functional Diagram

General Description

The HMC601LP4(E) Logarithmic Detector/Controller

converts RF signals at its input, to a proportional DC

voltage at its output. The HMC601LP4(E) employ

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 19mV/dB and an intercept of

-100dBm. The HMC601LP4(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.

The HMC601LP4(E) provides a 15/34ns (rise/fall time)

response time enabling RF burst detection to a pulse

rate beyond 20 MHz.
