RMS POWER DETECTOR &
ENVELOPE TRACKER, DC - 3.9 GHz
General Descriptions
Features
Functional Diagram
the HMc1021LP4e is an rMs power detector with
an integrated high bandwidth envelope detector. the
rMs output is a temperature compensated, monoton-
ic, linear-in-dB representation of real rF signal power,
measured over an input sensing range of 70 dB. the
envelope detector provides an accurate voltage output
which is linearly proportional to the envelope ampli-
tude of the rF input signal for modulation bandwidths
up to 150 MHz. the high bandwidth envelope detec-
tion of the HMc1021LP4e makes it ideal for detecting
broadband and high crest factor rF signals commonly
used in cDMA2000, wcDMA, and Lte systems. Ad-
ditionally, the instantaneous envelope output can be
used to create fast, excessive rF power protection,
PA linearization, and efficiency enhancing envelope-
tracking PA implementations.
the HMc1021LP4e’s rMs detector integration band-
width is digitally programmable via input pins scI1-4
over a range of more than 4 decades. this allows the
user to dynamically set the operation bandwidth and
also permits the detection of different types of modula-
tions on the same platform.
the HMc1021LP4e features an internal op-amp at the
rMs output stage, which accommodates slope and
intercept adjustments and supports a wide range of
applications.
