RF Power Amplifier design strives for the highest possible efficiency.
Operating Modes of Dynamic Power Supply Transmitter Amplifiers
Any amplifier operated with a varying supply voltage is actually a three-port circuit, having two inputs and one output. When an amplifier is characterized as a three-port for dynamic supply voltage operation, three separate operating modes...
Use this handy Smith Chart web app to create matching networks. Easiest tool to use: drag elements right on the chart! Supports multiple frequencies, transmission line elements, etc.
Online Smith Chart course now available at Udemy.
Reviewing the previous edition, IEEE Microwave Magazine boasted, "anyone designing power amplifiers will find this book thought provoking and useful."
The second of two volumes, this is a comprehensive treatment of nonlinear circuits, introducing the advanced topics that professionals need to understand for their RF (radio frequency) circuit design work. It presents an introduction to active RF devices and their modelling, and explores nonlinear circuit simulation techniques. Design techniques are addressed for RF transistor amplifiers, oscillators, mixers and frequency multipliers.
In this tutorial from High Frequency Electronics magazine, Anthony Bichler describes a technique to achieve broadband matching networks using the Smith Chart. The tutorial article also includes a review of Smith Chart fundamentals. The technique that is described goes beyond simply keeping the quality factor of the network to a minimum.
