RMS POWER DETECTOR
SINGLE-ENDED, DC - 3.9 GHz
Application Information
Principle of Operation
11
The HMC1020LP4E power detector is the optimal solution for monitoring and controlling transmitted and received
signal power, measuring the incident RF signal power, and then generating an output signal representing the input
power level.
The HMC1020LP4E is a monolithic true-RMS detector, which in fact is an analog calculator, designed to measure
the actual RMS power of the input signal, independent of the modulated signal waveform complexity or modulation
scheme. At the core of an RMS detector is a full-wave rectifier, log/antilog circuit, and an integrator. The RMS output
signal is directly proportional to the logarithm of the time-average of V IN2 . 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 HMC1020LP4E 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 HMC1020LP4E’s
RMSOUT output and the RF input power is given below:
P IN = RMSOUT / [log-slope] + [log-intercept], dBm
Configuration For The Typical Application
The HMC1020LP4E 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 HMC1020LP4E eliminates the requirement for an external
balun transformer or a matching network. The HMC1020LP4E 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.
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.
