Problems solved by technology

[0004] Among the microwave synthesizers with high power capacity published internationally in recent years, there are typically synthesizers that couple two orthogonally polarized TE11 modes into the same waveguide, and couple two TE11 modes that are relatively close to the frequency through an overmodulated rectangular waveguide. High-power beat-wave synthesizers, and synthesizers based on overmodulated circular waveguide filter structures, but the above-mentioned synthesizers all have common shortcomings, that is, they are bulky and have limited power capacity, and the isolation between different ports is difficult to guarantee , and the reflection coefficient is high, causing many adverse effects on microwave synthesis
