Part Number: LMH2110
Function: LMH2110 8 GHz Logarithmic RMS Power Detector with 45 dB dynamic range
Package: Tiny 6-bump DSBGA Type
Manufacturer: Texas Instruments
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 dBm and is ideally suited for use in combination with a directional coupler. Alternatively a resistive divider can be used as well.
