Miniaturized high-power isolated synthetic network device and implementation method

Abstract

The invention discloses a miniaturized high-power isolated synthetic network device and an implementation method. The method comprises the following steps: providing a lower cavity and an upper cavity; milling the opposite surfaces of the lower cavity and the upper cavity to form first vertical channel I-IV, first horizontal channel I-IV, a second vertical channel I, a second vertical channel II,a second horizontal channel I, a second horizontal channel II and a third vertical channel on the opposite surfaces, and arranging an E-arm spacer structure to form E-arm branch waveguide ports I-IV on one side of the lower cavity and the upper cavity in the length direction and an E-arm waveguide port on the other side; arranging the E-arm branch waveguide ports at equal intervals along a straight line; and assembling the lower cavity and the upper cavity to obtain the miniaturized high-power isolated synthetic network. The cavity is formed through one-time milling, network synthesis of fourports in the same plane is achieved through the channels, the E-arm spacer structures, the microstrip probes, the load resistors and the like, consistency of amplitude and phase of multiple branches and good isolation are guaranteed, the size is small, the frequency band is wide, and insertion loss is low.

technical field [0001] The invention belongs to the communication field and relates to waveguide synthesis / microwave power division technology, in particular to a miniaturized high-power isolation synthesis network device and a realization method. Background technique [0002] Waveguide synthesis is used to combine multiple channels of power to obtain greater power. The performance of the composite network, such as insertion loss, isolation, phase balance and amplitude balance, will have a greater impact on the performance of the entire system. The conventional T-junction is a three-port network, and there is no isolation between stages. When performing power synthesis, the inter-stage influence is greater; the current four-port synthesis network structure and implementation methods usually include E-arm, H-arm, branch waveguide and matching Structure and other ways to achieve, the structure is complex, the phase consistency of multi-branch is not ideal, and does not take i...
