Abstract

The invention discloses a millimeter-wave single-channel control TR component, which includes a component body. The upper side of the component body includes multiple groups of VM chips, TR chips and transmission line structures electrically connected to each other. A sub-board and a radio frequency power supply board are arranged on the lower side. A connector is arranged on the board, a DAC chip is arranged on the radio frequency power supply board, and the daughter board is electrically connected to the radio frequency power supply board; the upper side is opposite to the lower side. Corresponding to each group of radio frequency structures, a set of insulators are provided from the upper side of the component body to the lower side. The radio frequency power supply board is electrically connected to one end of each insulator, and the other end of each insulator is respectively connected to the VM chip and the corresponding radio frequency structure. The TR chip is electrically connected. The channel isolation, transceiver isolation, power supply and control signal and radio frequency signal isolation of TR components in this design can improve the control accuracy and operational reliability of TR components, save design space and production costs, and have good electromagnetic compatibility.

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

Embodiment 1

[0031] A millimeter-wave single-channel control TR component, see the attached Figure 1-7 , the TR component includes a component body, and the component body includes an upper side A and a lower side B. The upper side A and the lower side B are two parts divided by the component body from the middle part C. It should be noted that the " The middle part C" can be the middle of the component body, or other non-edge positions, as long as the electronic components in the upper side A and the electronic components in the lower side B can be isolated. Several groups of radio frequency structures are set on the upper side A of the component body, and the adjacent radio frequency structures are isolated from each other. The mutual isolation can be realized by setting metal plates, for example, to increase the isolation between channels. Each group of radio frequency structures includes a TR chip 21 , a VM chip 22 and a transmission line structure bonded to each other with gold wires...
