Part Number: LTC5582
Function: 40MHz to 10GHz, RMS Power Detector with 57dB Dynamic Range
Package: Small 3mm ×3mm DFN10
Manufacturer: Linear Technology, Analog Devices
Pinouts:
Description:
The LTC5582 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 LTC5582 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.
Application Circuits :
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. It is pin-to-pin compatible with the LT5570.
Features:
1. Frequency Range: 40MHz to 10GHz
