Doherty Power Amplifiers: From Fundamentals to Advanced Design Methods

Presenting both the fundamentals and advanced design techniques of Doherty Power Amplifiers technology, this book is a great resource for 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 behaviours based on a transistor. The different transconductance requirements for carrier and peaking amplifiers, reactive element effect, and knee voltage effect are described. Several methods to correct the imperfections are introduced, such as uneven input drive, gate bias adaptation, dual input drive, and the offset line technique. Advanced design methods of Doherty Amplifiers are explained and include multistage/multiway Doherty power amplifiers - which can enhance the efficiency of the amplification of a highly-modulated signal - signal tracking operation which increases the dynamic range, highly efficient saturated amplifiers, and broadband amplifiers. The Doherty amplifier on a chip for handset applications is also covered.
