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 power in dBm.
The LMH2110's excellent conformance to a logarithmic response enables an easy integration by using slope and intercept only, reducing calibration effort significantly.
The device operates with a single supply from 2.
7V to 5V.
The LMH2110 has an RF power detection range from -40 dBm to 5 dB...
