Design Study of an Endless RF Phase Shifter Using Ferroelectric Capacitors
Ilan Ben-Zvi
An endless radio-frequency (RF) phase shifter is designed using ferroelectric capacitors. An endless phase winds continuously and without bound while every control voltage executes…
Design of a High-Average-Power Ferroelectric Phase Shifter
Ilan Ben-Zvi, Alick Macpherson, Samuel Smith
This paper describes performance of a voltage controlled phase shifter designed for a high average power and a high figure of merit. The device is a reflection-type, resonant phase…
Design of a Fast Reactive Tuner for 1.3 GHz TESLA cavities at MESA
Ricardo Monroy-Villa, Ilan Ben-Zvi, Florian Hug +1
This work presents a state-of-the-art design of a Ferroelectric Fast Reactive Tuner (FE-FRT), capable of modulating high reactive power in TESLA type cavities on a microsecond time…
Detailed Design and Optimization of Ferro-Electric Tuners
Ilan Ben-Zvi, Alick Macpherson, Samuel Smith
A detailed, step-by-step design methodology of a Ferroelectric Fast Reactive Tuner (FE-FRT) capable of modulating Mega VAR reactive powers on a sub-microsecond time scale is given.…
High Power Fast Frequency Modulation
Ilan Ben-Zvi, Nicholas Shipman
A fast and highly efficient frequency modulation at a high power level is described. The system incorporates ferroelectric phase shifters and a magic-T or a circulator. A magnetron…
Magnetron Stabilization using Frequency Modulation
Ilan Ben-Zvi
An unstable magnetron RF source for driving an accelerator cavity at high power is stabilized using ferroelectric fast reactive tuning. The magnetron output is converted to a selec…
