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
• signals.

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.
