Application Information
PIN = VRMS / [log-slope] + [log-intercept], dBm
Monolithic true-RMS detectors are in-effect analog calculators, calculating the RMS value of the input signal, unlike
other types of power detectors which are designed to respond to the RF signal envelope. 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 VIN2. 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 signals can be measured accurately.
Configuration For The Typical Application
The RF input can be connected in either a differential or single-ended configuration: see “RF Input Interface” section
for details on each input configuration.
Typically the RMS output signal is connected directly to VSET, providing a PinVRMS transfer characteristic slope of
36.5mV/dBm. The log-slope is not adjustable internally, however an external method for adjusting log-slope, and log-
intercept is described in the “log-slope and intercept” section.
VTGT is also typically connected directly to VREF, however the VTGT voltage can be adjusted to optimize output
accuracy: see “Adjusting VTGT for greater precision” section for details.
Due to part-to-part variations in log-slope and log-intercept, a system-level calibration is recommended to satisfy
absolute accuracy requirements: refer to the “System Calibration” section for more details.
