White Paper: Microwave Power Amplifier Fundamentals

An amplifier is one of the most common electrical elements in any system. The requirements for amplification are as varied as the systems where they are used. Amplifiers are available in a large number of form factors ranging from miniscule ICs to the largest high-power transmitter amplifiers. In this article, the focus will be on solid-state power amplifiers used at microwave frequencies, particularly in test and measurement applications.
