What:

New Application Note Explains How to Design a Modified Three-Level Doherty Amplifier Using NI AWR Software - RF CafeToday's communication systems often use complex modulation techniques with peak-to-average ratio (PAR) signals of 9 dB and higher, requiring power amplifiers (PAs) in these systems to operate below the power levels that would yield optimum power-added efficiency (PAE). This application note presents a modified three-level Doherty amplifier as an alternative to the conventional three-way Doherty amplifier. The operating principle of the modified amplifier, which produces good efficiency over the top 10 dB of operation, is explained and the design challenges faced with this type of amplifier are discussed.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
