Hello,

I need help about RF envelope detector design. I have to design it in order to implement an envelop tracking system with a RF power amplifier.

Does somebody have experience in envelope detector design with 3G input signal for example?

What kind of circuit is able to detect envelope and control a DC DC converter?

thank you
 

envelope detector

check the application notes by avago and skyworks about the detectors using schottky diodes , they are used in the power detection in current mobile phones for CDMA and WCDMA , i have been working with those months ago

chekc this link


about the control , the output of the dtector usually converter to digital information and the base band processor use these info to control the PA and tranmit power
