Abstract
A Doherty amplifier is provided with a clipping circuit for making signal power flow to ground if the signal power becomes equal to or higher than a predetermine value in order to prevent a carrier amplifier, which is a small amplifier, from being destroyed if the signal power is increased to a sevenfold to tenfold multiple of a ratio of the size of the carrier amplifier to that of a peak amplifier.
