In BEPC II(Upgrade of Beijing Electron-Position Collider), multi-bunches and high current operation mode is usually used. Due to the influence of high frequency cavity structure or resistance impedance, the beam will be unstable. If the beam is unstable, the luminosity and brightness of the accelerator will be decreased. In order to improve the beam current and brightness of accelerator and the collider luminosity, the beam feedback system is needed to suppress the instability.
The trifold frequency multiplier by using triode is simple to operate, and it has good performance. In the experiments, the 500MHz signal was passed through the Triode Frequency Multiplier to get the 1.5GHz signal, and its output amplitude stability is 1.7mV, and its synchronization stability is 3.46ps compared with the 500MHz input signal.
