Definition. Class D amplifiers are those that output a switching waveform, at a frequency far higher than the highest audio signal that needs to be reproduced.

GaN, or Gallium Nitride, is a semiconductor material that maximizes power density. By using GaN devices in a radio frequency (RF) amplifier, high-output power can be achieved without increasing size and weight. This is ideal for applications requiring maximum RF power density, such as active antenna arrays.
