With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

Evaluating S-parameters and other CW stimulus responses is essential for characterising rf amplifiers. An rf vector network analyser (VNA) plays a critical role for this purpose, and proper ...

This article presents the challenges in designing RF power amplifier efficiency. It briefly describes the use of different amplifiers and techniques to create an effective result. This article ...

The basic laws of thermodynamics ensure that no electronic device can achieve 100% efficiency– although switch-mode power supplies come close (approaching 98%). Unfortunately, anything that generates ...

What every RF design engineer needs these days is a good all-purpose IC RF amplifier. You don’t want to have to design basic circuits like this yourself. Yet the need is always there for a gain block ...
