A power balanced photonic RF phase shifter includes: a microwave drive; a phase controller operably connected to the microwave drive; and a linearizing arm connected in parallel with the microwave drive, the linearizing arm operating under a bias voltage, V, that is controlled such that power variations of the photonic RF phase shifter are mitigated. In a preferred embodiment, the bias voltage, V, is controlled to keep an optical phase of the photonic RF phase shifter at a constant value. In a preferred embodiment, the microwave drive, the phase controller and the linearizing arm comprise (three) Mach-Zehnder modulators.
