| We have developed high power vacuum circulator for useful exchanging from pressure type (SF6) waveguide to vacuum type component. We measured tune shift of ferrite occurred by high magnetic field which is excited by input RF high power. This tune shift limit handling power at range of center value ±10MW in case of Y-junction type circulator. In order to attach more high power circulator, we have developed 4 port type vacuum circulator. We measured amount of phase shift depended on input RF power in case of vacuum phase shifter. This result show us maximum handling power of 40MW for 4 port type circulator. |
