Example Embodiment

[0030] Example one

[0031] One millimeter wave manifold control TR component, see attached Figure 1-7 The TR component includes a component body, the component body includes two parts of the upper side A and the lower side B, the upper side A and the lower side B, and the component body from the central portion C is required, and it is to be explained. The middle C "may be the front intermediate of the component body, or may be the position of other non-edge edges, as long as it is possible to isolate the electronic components in the upper side A and the electronic components in the lower side B. The upper side A of the component body is provided, and the adjacent radio frequency structure is separated between the adjacent radiofrequency structure, and the isolation between the channels can be achieved by setting a metal plate. Each set of radio frequency structures includes a TR chip 21, a VM chip 22, and a transmission line structure that bonded to each other. The transmission ...

[0034] Example 2

[0035] This example discloses the structure of the component body.

[0036] The component body includes an upper cavity 1 and a lower chamber 2, such as figure 1 ,3 4, said that the upper cavity 1 includes opposite surfaces 1b of the upper surface 1a of the upper cavity and the lower surface 1b of the upper cavity, the upper surface 1a of the upper cavity, and the lower surface 1b of the upper body body; the lower chamber 2 includes The lower surface 2a of the lower chamber and the lower surface 2b of the lower chamber, the upper surface 2a of the lower chamber and the lower surface 2b of the lower chamber are opposite. The lower surface 1b of the upper body is coupled to the upper surface 2a of the lower chamber, and the position is attached to the upper side A of the assembly body by the screw. The transmission line structure is disposed between the lower surface 1b of the upper cavity and the upper surface 2a of the lower chamber. The VM chip 22 and TR chip 2...

Example Embodiment

[0039] Example three

[0040] This embodiment is based on the design of 6 channels as an example (the amount of the remaining channel is similar), which discloses a W-band single-channel control TR component, such as Figure 1-7 As shown, including the upper cavity 1 and the lower cavity 2, the upper cavity 1 includes a lower surface 1a of the upper cavity, the lower surface 1b of the upper cavity, the upper surface 1a of the upper body and the lower surface of the upper body Relaterless; the lower chamber 2 includes the upper surface 2a of the lower cavity and the lower surface 2b of the lower chamber, the upper surface 2a of the lower chamber and the lower surface 2b of the lower chamber. The lower surface 1b of the upper body is coupled to the upper surface 2a of the lower chamber and is joined by a screw.

[0041] 6 sets of first waveguide structures 11a are provided on the lower surface 1b of the upper body, each of which is constituted by one-half of the 6 sets of waveguide s...

Abstract

The millimeter wave single-channel control TR assembly comprises an assembly body, the upper side of the assembly body comprises a plurality of groups of VM chips, TR chips and transmission line structures which are electrically connected with one another, the lower side of the assembly body is provided with a daughter board and a radio frequency power supply board, the daughter board is provided with a connector, the radio frequency power supply board is provided with a DAC chip, and the daughter board is electrically connected with the radio frequency power supply board; the upper side and the lower side are opposite. Corresponding to each group of radio frequency structures, a group of insulators are arranged from the upper side to the lower side of the assembly body in a penetrating manner, the radio frequency power supply board is electrically connected with one end of each insulator, and the other end of each insulator is electrically connected with the VM chip and the TR chip of the corresponding radio frequency structure. According to the TR assembly, isolation between channels, transceiving isolation and isolation between power supply and control signals and radio-frequency signals are achieved, the control precision and the operational reliability of the TR assembly can be improved, the design space and the manufacturing cost are saved, and the electromagnetic compatibility is good.

Description

technical field [0001] The invention relates to the field of millimeter-wave radar, in particular to a millimeter-wave single-channel control TR assembly. Background technique [0002] Millimeter wave has the advantages of wide frequency band, short wavelength and high resolution. In recent years, it has developed rapidly in the fields of radar, communication, and remote sensing. As a key part of millimeter wave radar, the front end of millimeter wave antenna is more and more worthy of people's attention. focus on. As the core component of the millimeter-wave antenna front-end, the millimeter-wave TR component has higher and higher performance requirements. It is increasingly difficult for the current millimeter-wave TR component to meet the demand. Contents of the invention [0003] The object of the present invention is to provide a millimeter-wave single-channel control TR assembly to improve the electromagnetic compatibility, control accuracy and reliability of the TR...
