Title: Key Test Requirements of Modem Handset Power Amplifiers.
Authors: Hall, David A.1, Nelson, Haydn1, Pailloncy, Guillaume1
Source: Microwave Journal. Jun2014, Vol. 57 Issue 6, p70-82. 7p.
Subjects: Materials testing, Power amplifiers, Technological innovations, Electric distortion, Cell phones
Abstract: The article discusses the developments of technologies that are driving modern cellular handset power amplifier (PA) test requirements including digital pre-distortion (DPD) testing, envelope tracking (ET) characterization, and load pull. It mentions the capability of load pull to improve the overall efficiency of the device. It suggests the need for engineers to understand how to characterize PAs designed to operate under DPD and ET conditions.
