5582 TA01a LTC5582 40MHz to 10GHz RMS Power Detector with 57dB Dynamic Range FEATURES DESCRIPTION n Frequency Range: 40MHz to 10GHz The LTC 5582 is a 40MHz to 10GHz RMS responding n Linear Dynamic Range: Up to 57dB power detector. It is capable of accurate power measure- n Accurate RMS Power Measurement of High Crest ment of an AC signal with wide dynamic range, from Factor Modulated Waveforms 60dBm to 2dBm depending on frequency. The power n Exceptional Accuracy Over Temperature: 0.5dB (Typ) of the AC signal in an equivalent decibel-scaled value n Low Linearity Error within Dynamic Range is precisely converted into DC voltage on a linear scale, n Single-Ended or Differential RF Inputs independent of the crest factor of the input signal wave- n Fast Response Time: 90ns Rise Time forms. The LTC5582 is suitable for precision RF power n Low Supply Current: 41.6mA at 3.3V (Typ) measurement and level control for a wide variety of RF n Small 3mm 3mm DFN10 standards, including LTE, WiMAX, W-CDMA, CDMA2000, n AEC-Q100 Qualified for Automotive Applications 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.
