Doherty power amplifiers (DPAs) have emerged as a critical technology for modern wireless communication systems, notably in the context of 5G and beyond. These amplifiers utilise a dual-amplifier ...

In just a few years’ time, so many things about wireless communication will be different from the way we know them today. Cellular networks, for example, traditionally made up primarily of larger base ...

Rohde & Schwarz is claiming to have invented a new test set-up for verifying power amplifier performance when connected to an antenna, which typically shows a dispersive impedance, by swapping the ...

A class-D puts out a pulse-width modulated (PWM) signal instead of the linear signal that is typical in class-AB amplifiers. The PWM signal contains the audio signal and the PWM switching frequency ...
