According to an exemplary embodiment, a balanced amplifier includes an in-phase amplifier coupled to a first input port of an output coupler and a quadrature amplifier coupled to a second input port of the output coupler. The balanced amplifier further includes an impedance termination coupled to an isolated port of the output coupler. The balanced amplifier further includes a protection circuit coupled to the isolated port of the output coupler and configured to limit an amount of power applied across the impedance termination. The balanced amplifier further includes an input coupler having a first output port coupled to an input of the in-phase amplifier and a second output port coupled to an input of the quadrature amplifier.
