LMH2120, 6 GHz Linear RMS Power Detector

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

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