Product Summary

The LTC5582IDD is a RMS Power Detector. The LTC5582IDD is a 40MHz to 10GHz RMS responding power detector. It is capable of accurate power measurement of an AC signal with wide dynamic range, from –60dBm to 2dBm depending on frequency. The power of the AC signal in an equivalent decibel-scaled value is precisely converted into DC voltage on a linear scale, independent of the crest factor of the input signal waveforms. The LTC5582IDD is suitable for precision RF power measurement and level control for a wide variety of RF standards, including LTE, WiMAX, W-CDMA, CDMA2000, TD-SCDMA, and EDGE. The DC output is buffered with a low output impedance amplifier capable of driving a high capacitance load. Consult factory for more information. The part is packaged in a 10-lead 3mm × 3mm DFN. The applications of the LTC5582IDD include RMS Power Measurement, PA Power Control, Receive and Transmit Gain Control, LTE, WiMAX, W-CDMA, CDMA2K, TD-SCDMA, EDGE Basestations, Point-to-Point Microwave Links and RF Instrumentation.
