The RMS output signal is typically connected to VSET through a resistive network providing a Pin -> RMSOUT
transfer characteristic slope of 35.2 mV/dB ( at 900 MHz). However the RMS output can be re-scaled to “magnify”
a specific portion of the input sensing range, and to fully utilize the dynamic range of the RMS output. Refer to the
section under the “log-slope and intercept” heading for details.

RMS POWER DETECTOR
SINGLE-ENDED, DC - 3.9 GHz
LOG-Slope and Intercept
The HMC1020LP4E provides for an adjustment of output scale with the use of an integrated operational amplifier.
Logarithmic slope and intercept can be adjusted to “magnify” a specific portion of the input sensing range, and to fully
uꢄilizꢀ ꢄhꢀ dynamiꢅ ꢃangꢀ ꢁf ꢄhꢀ rMs ꢁuꢄpuꢄ.
A log-slope of 35.2 mV/dB (@1900 MHz) is set by connecting RMS Output to VSET through a resistor network for ß=1
(see application schematic).
