±0.3dB Accurate RMS Power
Measurement to 2.7GHz
Exceptional Accuracy over Temperature from 40MHz to 2.7GHz, with
Fast 5µs Settling to 1dB Ripple
The LT®5570 provides fast, accurate RMS RF power measurements of high crest-factor modulated signals.
Its >50dB dynamic range meets the most demanding requirements of cellular basestations, WiMAX and
wireless infrastructure equipment. And its industry-leading accuracy performance over temperature simplifies
design and calibration procedures.
