There is an interesting 4-part series in the journal \"High\nFrequency Electronics\" that is a tutorial on various techniques to\nachieve high efficiency power amplifiers. The article mentions the\nDoherty technique from the 1930's which was the progenitor of Meinzer's\nHELAPS. To fetch the series, surf to\nhttp://www.rfcafe.com/references/magazine_articles/magazine_articles_2003.htm\nwhich leads to the 4-part article \"RF & Microwave Power Amplifier &\nTransmitter Technologies\".\n\n73, Tom\n", "attachments": [] }
