DataSheet.in LMH2110 PRODUCT BRIEF LMH2110 PRODUCT BRIEF January 7, 2010 8 GHz Logarithmic RMS Power Detector with 45 dB Dynamic Range General Description The LMH2110 is a 45 dB Logarithmic 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 8 GHz. It provides an accurate, temperature and supply insensitive, output voltage that relates linearly to the RF input...
