A balanced amplifier has two amplifying devices that are run in quadrature. That is, they are operating 90 degrees apart in transmission phase. A quadrature coupler or splitter on the input phase-shifts the two signals 90 degrees at the amplifier inputs, then a second quadrature coupler on the output “un-phase-shifts” the signals at the amplifier outputs so they combine in phase.
