RMS POWER DETECTOR &
ENVELOPE TRACKER, DC - 3.9 GHz
LOG-Slope and Intercept
The HMC1021LP4E provides for an adjustment of output scale with the use of an integrated operational amplifier.
Logslope and intercept can be adjusted to “magnify” a specific portion of the input sensing range, and to fully utilize
the dynamic range of the rMs output.
A log-slope of 37.3 mV/dB (@1900 MHz) is set by connecting RMS Output to VSET through a resistor network for =1
(see application schematic).
the log-slope is adjusted by applying the appropriate resistors on the rMs and Vset pins. Log-intercept is adjusted
by applying a Dc voltage to the Vset pin.
optimized slope =
* log-slope
Optimized intercept = log_intercept – (R
FBK /Rset ) * VBLINe
rFBK
rFBK // RsHUNt // Rset
= 1

when r
FBK=0 to set rMsoUt=Vset, then =1/2
If r
set is not populated, then = * (RFBK/ (RFBK // RsHUNt)) and intercept is at nominal value.
example: the logarithmic slope can be simply increased by choosing appropriate r
FBK and rsHUNt values while
not populating the rset resistor on the evaluation board to keep the intercept at nominal value.
setting r
FBK =4.7KΩ and rsHUNt = 2.2KΩ results in an optimized slope of:
Optimized Slope = * log_slope = 1.57* 37.3mV / dB
Optimized Slope = 58 mV / dB
