GaP monolithic integer-n synthesizer application as RF system master oscillator for linear electron accelerator

The main source of RF signal for electron linac is master oscillator which should have possibility of ongoing RF frequency adjustment according to actual conditions of the accelerator microwave system such as standing wave ratio variations caused by temperature change. The basis for the construction was GaP monolithic integer-N synthesizer and voltage controlled oscillator in one Analog Devices ADF4360 chip. The generator is easy operable by the user during machine tune-up procedure and produces RF signal in well-defined frequency step, at least 30dB distant from noise level.
