Tuning for phase shifters and stub lines
At AFT we define the notion "Fast Ferrite Tuner" (FFT) as an electronically controllable reflection phase shifter and
inductive stub lines made of ferrite filled waveguide structures.
These elements are equipped with a fast electromagnetic system and are primarily used in the following passive subsystems:
for automatic impedance matching of antennas and applicators
- for tuning of accelerator cavities
- for amplitude phase modulation (I-Q-modulation) of high-power
For these systems we develop overall solutions, which apart from the relevant microwave components
also include control electronics and if necessary power supply.
Example: I-Q-modulator for variation of amplitude and phase for scientific acceleration.
