Overview
 450 MHz to 6000 MHz Crest Factor Detector at Digi-Key Now, cell phone designers can manage wireless handset power more efficiently, extend battery life and better process complex 3G and emerging 4G cell phone signals, with ADI's ADL5502, one of the industry's first dual-function RF detectors in a single package that combines an RMS detector with an envelope detector to facilitate the crest-factor measurement of complex signals. ADL5502 Datasheet
The ADL5502 detector features a ±0.1 dB accuracy with crest factors up to 11 dB, which is five times more precise than competing devices. With the higher level of integration, cell phone users can expect up to 20 percent longer battery life. So now, cell phone manufacturers can reduce cost and development efforts by eliminating look-up tables and correction factors that otherwise would be required to accurately control transmitted power levels. The ADL5502 provides ±0.2 dB temperature stability from -40 °C to +85 °C, further reducing calibration routines while allowing handsets to operate more reliably over temperature.
