Push–pull amplifier
Push–pull amplifier an amplifier made up of two identical class b amplifiers operated as a balanced pair (180 degrees out of phase with each other) into a common load, resulting in each amplifier operating over alternating half cycles of the input signal, and having the output signal combined such that full cycles are dissipated across the load. Odd order harmonics are present at the load, while even order harmonics are suppressed, resulting in an output signal that is an odd order multiple of the input frequency (either a fundamental frequency amplifier or an odd order frequency multiplier).
