Practical Considerations on Wideband Switchmode High Power Solid-state Power Amplifiers

Modern wireless communication systems demand not only high efficient RF and microwave amplifiers, but wideband designs too. Switchmode power amplification classes can provide both benefits simultaneously, but theoretical knowledge must be combined with important practical considerations to get these advantages. There are important practical considerations that limit the theoretical...

Digital Feed-forward Linearization

The intention of this paper is to describe a concept of non-adaptive Digital Feed-forward Linearization, an approach intended to correct unwanted nonlinear effects in power amplifiers. The reason for calling the described approach “digital” is that its...
This paper describes a concept of non-adaptive Digital Feed-forward Linearization. A feed-forward amplifier is a system designed to reduce the spectrum re-grows appearing due to the amplifier’s nonlinearity. There are several general techniques to reduce nonlinearity effects. They are divided into two major groups. One of them (called “predistortion”)...
