ADI LTC5583IUF#PBF

40 МГц ~ 6 ГГцCDMA, LTE, W-CDMA, WiMAX-59 дБм ~ 4 дБм

Overview

The LTC5583IUF is a dual-channel RMS power detector, capable of measuring two AC signals with wide dynamic range, from –59dBm to 4dBm, depending on frequency. Each AC signal’s power in decibel-scaled value is precisely converted to a DC voltage on a linear scale, independent of the crest factor of the input signal waveforms. The LTC5583IUF is suitable for precision power measurement and level control for a variety of RF standards, including LTE, EDGE, W-CDMA, CDMA2000, TD-SCDMA, and WiMAX.

The power difference of the two input signals is provided at a difference output pin. Each channel also has a fast envelope detector, which tracks the RF input signal’s envelope and outputs a voltage directly proportional to the signal’s instantaneous power. The envelope detectors can be disabled to reduce power consumption.
