LMH2120 Datasheet Linear Rms Power Detector

Manufacturer: Texas Instruments

Overview: LMH2120 www.ti.com SNWS021C – JULY 2010 – REVISED FEBRUARY 2013 LMH2120 6 GHz Linear RMS Power Detector with 40 dB Dynamic Range Check for Samples:.

General Description

The LMH2120 is a 40 dB Linear RMS power detector particularly suited for accurate power measurement of modulated RF signals that exhibit large peak-toaverage ratios, i.e, large variations of the signal envelope.

Such signals are encountered in W-CDMA and LTE cell phones.

The RMS measurement topology inherently ensures a modulation insensitive measurement.
