Abstract

The invention discloses a bidirectional coupling detector and method based on a rectangular waveguide, and relates to the technical field of bidirectional coupling detectors. The bidirectional coupling detector comprises a detector which comprises a microwave circuit, and the bidirectional coupling detector also comprises a bidirectional waveguide coupler. The bidirectional waveguide coupler comprises a main cavity, the main cavity is provided with a main path straight-through waveguide, and the two ends of the main path straight-through waveguide are an input waveguide and an output waveguiderespectively. Coupling branches are arranged on the two sides of the main path straight-through waveguide. Each coupling branch is connected with the detector. The detector also comprises side cavities. The side cavities are each provided with at least two waveguide grooves. Each waveguide groove and the coupling branch corresponding to the side cavity form a coupling port and an isolation port.The bidirectional coupling detector based on a rectangular waveguide is high in integration level. The bidirectional coupler and the detector are designed in a combined mode in structure. The size isreduced, the installation complexity is reduced, and the assembly precision of the assembly is guaranteed.

Description

technical field [0001] The invention relates to the technical field of dual-directional coupling detectors, in particular to a rectangular waveguide-based bidirectional coupling detector and method. Background technique [0002] The waveguide coupling detector is a component widely used in millimeter wave systems. Its function is to distribute the signal on the main transmission path to the coupling port in a certain proportion, and detect the signal at the coupling port. After detection, the corresponding DC voltage is generally obtained. Report extension or system for equipment status monitoring or automatic control. [0003] For millimeter-wave power amplifier components, it is usually required to perform bidirectional detection of the output signal and reflected signal at the output port in order to control the output status and reflection of the device. If the output power is abnormal or the reflection is large, turn off the device in time and check repair. [0004] T...
