6 Stepless Small Stage 1100w Digital Power Amplifiers

 

In digital power amplifiers the analog signal is not handled directly but encoded in a pulse train. It is restored only at the output by a bandpass filter. Due to the discretization in amplitude, this principle, often referred to as class D, allows for efficient and versatile amplifiers. While in widespread use for audio frequencies, digital PAs have been introduced at microwave frequencies only a few years ago.
