Embodiment Construction
[0026] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0027] As shown in Figure 1, the one-to-four coaxial impedance converter includes a coaxial line on which a ferrite magnetic ring is arranged; the inner conductor 1 at one end of the coaxial line and the outer conductor at the other end 4 are connected, and connected to the microstrip line whose characteristic impedance at the input end is α, the outer conductor 2 is connected to the output I road, and the inner conductor 3 is connected to the output II road. Among them, taking α as 50 ohms as an example, the power distribution and combiner composed of the following one-to-coaxial impedance converter and one-to-four coaxial impedance converter and one-to-coaxial impedance converter are all the same as one-to-four The output impedance of the coaxial impedance converter is matched.
[0028] A one-to-coaxial impedance converter, including two coaxial lines A an...
