In audio applications there is a trend towards Class D audio amplifiers as replacements for traditional Class AB electronics. The main driving forces are improved efficiency and space savings.

The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. In this ...

The process of designing traditional fixed-supplypower amplifiers has been well-establishedfor many years. Well-definedmetrics for performance assessment exist,and the amplifier designer’s job is to ...

Over the years, tutorials have appeared in EMC journals explaining how to estimate the power required from a power amplifier intended for use in an RF immunity test system. Little material, if any, ...
