What's a Doherty power amplifier? What's the practical design flow to develop a DPA? May I estimate the achievable performance? May I get more efficiency, gain, back-off and frequencies from my DPA? Whether you have a FAQ or a rare question, inside you'll probably find the answer. This book is a real design manual, which can help the designer to identify, starting from the desired requirements, the best approach to use, simultaneously highlighting the advantages as well as disadvantages that occurs with its adoption.

Doherty Power Amplifiers: From Fundamentals to Advanced Design Methods is a great resource for both RF and microwave engineers and graduate students who want to understand and implement the technology into future base station and mobile handset systems. The book introduces the very basic operational principles of the Doherty Amplifier and its non-ideal behaviors. The different transconductance requirements for carrier and peaking amplifiers, reactive element effect, and knee voltage effect are described. In addition, several methods to correct imperfections are introduced, such as uneven input drive, gate bias adaptation, dual input drive and the offset line technique. Advanced design method...
