Abstract

In this letter, a broadband waveguide magic-T with compact size is presented. A grounded suspended stripline has been used to obtain broadband isolation characteristics and increase power capacity. The inner ridge-matching structure is used to achieve broadband matching. The method and design process of the demonstrated magic-T are described in detail. The measured 15-dB bandwidth is about 30.3%, almost for waveguide BJ-320 waveguide operating bandwidth. The measured isolation between sum and deference ports is above 37.5 dB; 20-dB measured isolation is achieved between collinear ports. The measured and simulated results are in good agreement. It has advantages in high-power applications.

具有紧凑内脊匹配的宽带Ka波段波导Magic-T

在这封信中，提出了一种尺寸紧凑的宽带波导magic-T。为了获得宽带隔离特性并提高功率容量，已经使用了接地的悬挂带状线。内脊匹配结构用于实现宽带匹配。详细介绍了演示的magic-T的方法和设计过程。测得的15dB带宽约为30.3%，几乎适用于波导BJ-320波导的工作带宽。测量的和端口和差端口之间的隔离度高于37.5dB；在共线端口之间实现了20dB的测量隔离。测量结果与模拟结果吻合良好。它在高功率应用中具有优势。

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
