研究目的
To enhance the high-power performance of the ferrite phase shifter (PS) by increasing the waveguide height.
研究成果
The study demonstrates that increasing the waveguide height of the ferrite phase shifter can enhance its peak-power-capacity without increasing the insertion loss or decreasing the differential phase shift. This provides an effective approach for high-power design of remanent ferrite phase shifters.
研究不足
The study focuses on the enhancement of peak power capacity by increasing the waveguide height, but does not explore other potential methods for improving high-power performance. The impact of higher order modes on the performance of the PS is noted but not extensively analyzed.
1：Experimental Design and Method Selection:
The study utilizes dual-toroid geometry as a high-power structure. Two configurations of X-band PSs with full-height (FH) and increased-height (IH) waveguides are designed and fabricated while keeping other parameters consistent.
2：Sample Selection and Data Sources:
The study involves the fabrication of two types of PSs (FHPS and IHPS) with the same geometrical dimensions and material parameters except for waveguide height.
3：List of Experimental Equipment and Materials:
An X-band klystron is used as a microwave source. The PSs are tested at a pulse width of 1 μs and a repetition frequency of 100 Hz.
4：Experimental Procedures and Operational Workflow:
The incident wave, reflected wave, and transmitted wave are measured, and the insertion loss is calculated. The presence of voltage breakdown is judged based on the waveforms.
5：Data Analysis Methods:
The performance of the PSs is analyzed based on simulation and high-power experiments. The insertion loss and differential phase shift (DPS) are key metrics.
