Embodiment Construction
[0023] Specific embodiments and effects of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0024] refer to figure 1 , the high-power microwave rectifier circuit with multi-gallium nitride Schottky diode series-parallel structure of the present invention includes an input port 1, a matching circuit 2, a DC blocking capacitor 3, an input filter 4, a rectifier 5, an output filter 6 and load 7, wherein:
[0025] The input port 1 adopts an SMA female coaxial connector.
[0026] The matching circuit 2 adopts an open-circuit stub matching structure, its left end is connected to the input port 1, and its right end is connected to the input filter 4 through a DC blocking capacitor 3. In this example, a high-frequency ceramic capacitor of 2.7pF is selected but not limited to.
[0027] The input filter 4 adopts a low-pass filter, which is used to suppress the passage of microwave signals greater than the operating frequency a...
