<p>A coupled-cavity circuit (10) for a microwave electron tube is shown having one or more cavities (36) whose cross-sections are polygonally shaped, such as rectangles. Located in one or more corners of the polygonally shaped cavities (36) are irises (50) which have a higher resonant frequency. These irises (50) are generally triangularly shaped with rounded corners and one leg of the triangle rounded about the drift tube (38) of the microwave electron tube.</p> |
