DataSheet.in LMH2120 6 GHz Linear RMS Power Detector with 40 dB Dynamic Range July 20, 2010 LMH2120 6 GHz Linear RMS Power Detector with 40 dB Dynamic Range 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-to-average 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. The device has an RF frequency range from 50 MHz to 6 GHz. It provides an accurate, temperature and supply insensitive, output voltage that relates linearly to...
