LMH2110TM/NOPB

The LMH2110TM/NOPB is a 8GHz Logarithmic RMS Power Detector with 45dB dynamic range. The logarithmic RMS power detector particularly suited for accurate power measurement of modulated RF signals that exhibit large peak-to-average ratios, that is, 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 50MHz to 8GHz. It provides an accurate, temperature and supply insensitive output voltage that relates linearly to the RF input power in dBm. The LMH2110 device has excellent conformance to a logarithmic response, enabling easy integration by using slope and intercept only, reducing calibration effort significantly. The device operates with a single supply from 2.7 to 5V. The LMH2110 has an RF power detection range from -40 to 5dBm and is ideally suited for use in combination with a directional coupler.
