HMC1021LP4E

RMS POWER DETECTOR &
ENVELOPE TRACKER, DC - 3.9 GHz
the HMc1021LP4e combines an rMs detector core with an envelope Detector in a single package which is capable
of extracting envelope information of the modulated rF signal with modulation bandwidths in excess of 100 MHz. the
extracted envelope information is independent of the average power and the crest factor of the rF signal. the rMs
detector core provides a linear-in-dB output of the average rF power, whereas the envelope detector core provides
a linear representation of the instantaneous envelope waveform. the instantaneous envelope output etoUt may be
used in ultra-fast excessive RF power protection systems, PA linearization techniques and in efficiency enhancing
envelope-tracking PA implementations.
the HMc1021LP4e’s rMs detector core is designed to measure the actual rMs power of the input signal,
independent of the modulated signal waveform complexity or modulation scheme. the rMs detector core architecture
of HMC1021LP4E is composed of a full-wave rectifier, log/antilog circuit, and an integrator as shown above. The
rMsoUt signal is directly proportional to the logarithm of the time-average of V
IN
2
. the bias block also contains
temperature compensation circuits which stabilize output accuracy over the entire operating temperature range. the
Dc offset cancellation circuit actively cancels internal offsets so that even very small input signal levels can be
measured accurately.
the HMc1021LP4e achieves exceptional rF power measurement accuracy independent of the modulation of the
carrier with the system architecture shown in the block diagram figure. The relation between the HMC1021LP4E’s
rMsoUt output and the rF input power is given below:
Configuration For The Typical Application
the HMc1021LP4e is a logarithmic rMs detector that can be directly driven with a single-ended 50-ohm rF source.
The integrated broadband single-ended input interface of HMC1021LP4E eliminates the requirement for an external
balun transformer or matching network. the HMc1021LP4e can be operated from Dc to 3.9 GHz by using only
standard Dc blocking capacitors. this simple input interface provides cost and PcB area reductions and increases
measurement repeatability.
