An RF amplifier system and method for varying the phase of an RF signal made up of a first train of pulses exhibiting a fixed frequency and fixed duty pulse cycle and wherein each pulse is of a fixed amplitude and duration. An integrator converts each pulse cycle of the RF signal into a dual slope symmetrical ramp signal. A first level signal and a second level signal are provided and are equally spaced from a reference level. The dual slope ramp signal is compared with the first and second level signals. A first pulse signal is provided for a time duration corresponding with the time duration that the ramp signal exceeds the first level signal and a second pulse signal is provided for a time duration corresponding with the time duration that the second level signal exceeds the lamp signal. First and second pulse generators respectively receive the first and second pulse signals and provide first and second trigger pulses. A bistable circuit responds to the first and second trigger pulses to be in respective first and second states and provide an output RF signal made up of a second train of pulses shifted in phase from the first train by an amount related to the magnitude of the first level signal or the second level signal.
