Abstract
A power amplifier circuit uses an output transistor and a cascode transistor. First and second drive circuits apply gate control signals to the two transistors, which rise and fall in synchronism, and this is such that the voltage drop across the cascode transistor is reduced (compared to a constant gate voltage being applied to the output transistor).
