RF Power Amplification 101: Handling Non-Idealities

RF Power Amplification 101: Handling Non-Idealities

October 27, 2021

Aerospace & Defense, Communications

When amplifiers are introduced in any basic tutorial, the discussion often assumes ideal transistors are being used. The previous two articles in this series on RF power amplifier (PA) basics made such assumptions both to classify amplifiers based on gate bias and calculate their best-case efficiencies. If these assumptions were to form the basis of selecting amplifier mode of operation or gate biasing, engineers would indeed be in for a surprise from actual designs.

The third and final part in this series takes real-world waveforms and transistor behavior into account as it revisits gate biasing and efficiency.
