Embodiment Construction
[0017] Such as figure 1 As shown, a multi-path waveguide power combiner amplifier includes a radial waveguide power divider 1, a radial waveguide power combiner 2 and an amplifier chip array 3.
[0018] Such as figure 2 As shown, the structure of the radial waveguide power splitter and the radial waveguide power combiner are exactly the same, specifically: including a side metal wall 5, an upper metal wall 4, and a lower metal wall 6; the side metal wall 5 is a cylindrical metal tube , The upper metal wall 4 and the lower metal wall 6 are round metal sheets with the same diameter as the outer diameter of the side metal wall 5. The upper metal wall 4 and the lower metal wall 6 are respectively fixed on the two ends of the side metal wall 5. The upper metal wall 4 The inner surface of the lower metal wall 6 and the inner surface of the side metal wall 5 enclose a cylindrical radial waveguide cavity. The center of the outer surface of the upper metal wall 4 is fixedly provided wit...
