Doherty Amplifiers and Measurement-Aided Development

 

This webinar introduces the Doherty amplifier as a special case of the “balanced” amplifier genre. The speakers discuss design & test challenges and show implementation variants that make it possible to increase output power and improve efficiency.

Using a dual input Doherty measurement setup as a reference, Rohde & Schwarz describes a measurement-aided design method that can significantly reduce the time to market. Key topics such as calibration, linear and nonlinear measurements, and analysis round out the pragmatic approach.
