Abstract

In this paper a 250W solid state RF Pulse Power Source (PPS) operating over a 2995MHz to 3001MHz frequency range with only 100Hz frequency step and from 5.6μs to 8.4μs pulse width at the duty cycle below 0.5% is presented. The device was optimized to deliver the synchronized high-frequency-stability RF pulse for Linear Accelerator processing. The pulse power level can be controlled within 18dB dynamic range with power drop during the pulse less than 0.3dB. The phase noise level and long-term stability including VCO pulling effect of the synthesized RF signal is below -85dBc/Hz@1kHz and less than 0.2ppm, respectively. The advanced reconfiguration, diagnostic and protection features built into the RF pulse source are remotely controlled via Ethernet.
