Embodiment 1

[0030] Such as Figure 1-4 As shown, a tile type TR module for vertical transmission of radio frequency signals includes a housing 1 in which an upper chamber 11 and a lower chamber 12 are provided along the thickness direction of the module, and the upper chamber 11 Both the lower chamber 12 and the lower chamber 12 penetrate the surface of the housing 1 and have opposite opening directions. The upper chamber 11 is provided with a radio frequency link 2 and a radio frequency input connector 3, and the lower chamber 12 is provided with a switching microstrip 4. The upper chamber 11 is closed by a cover plate 5 embedded in the opening of the upper chamber 11, and the lower chamber 12 is closed by a sealing plate 6 embedded in the opening of the lower chamber 12 to realize the air of the TR module. Sealed, the transfer microstrip 4 is connected to the radio frequency link 2 and the radio frequency input connector 3 by perforation soldering to realize the signal transmission conne...

Embodiment 2

[0038] Such as Figure 1-4 As shown, a tile type TR module for vertical transmission of radio frequency signals in this embodiment has the same structure as Embodiment 1, except that it further includes an insulator 7 that penetrates the upper chamber 11 and the lower chamber 12, and the insulator 7 One end is connected with the radio frequency link 2, and the other end is connected with the transfer microstrip 4 by through-hole soldering.

[0039] The tile type TR module for vertical transmission of radio frequency signals in this embodiment uses an insulator 7 to connect the radio frequency link 2 and the switching microstrip 4, which has a simple structure and facilitates the connection of the radio frequency link 2 and the switching microstrip 4. Improve the production efficiency of the TR module. When preparing the TR module, a hole-like structure is set in the housing 1 in advance to connect the upper chamber 11 and the lower chamber 12, and then the insulator 7 is connecte...

Embodiment 3

[0042] Such as Figure 1-4 As shown, a tile-type TR module for vertical transmission of radio frequency signals in this embodiment has the same structure as Embodiment 2, except that it further includes a low-frequency input connector 8, which penetrates behind the cover plate 5. Connected to the radio frequency link 2, the contact surface of the low frequency input connector 8 and the cover plate 5 is connected by gold tin welding, and the low frequency input connector 8 is a glass sintered pin header.

[0043] In this embodiment, a tile type TR module for vertical transmission of radio frequency signals uses glass sintered pin headers as the low frequency input connector 8 so that the pins of the low frequency input connector 8 are connected to the radio frequency link in a direction perpendicular to the module array 2 connection to realize the vertical input of low-frequency signals, so that the RF input signal and low-frequency input signal of the TR module of this structure ...

Abstract

The invention relates to the field of tile type active phased-array antenna, and particularly relates to a tile type TR module capable of realizing radio-frequency signal vertical transmission. The module comprises a shell, the shell is internally provided with an upper chamber and a lower chamber, the upper chamber is internally provided with a radio frequency link and a radio frequency input connector, the lower chamber is internally provided with a change-over microstrip, the change-over microstrip is respectively in signal transmission connection with the radio frequency link and the radiofrequency input connector, thus, transmission of the radio frequency signal is on the same part, devices are arranged closely, integration level is relatively high, and structure form space is compact, stability and reliability of signal transmission are guaranteed, moreover, the shell is simple in structure, improvement of production efficiency of the module is facilitated, moreover, the radio frequency signal is subjected to vertical transition twice and then input to the radio frequency link, thus, vertical input of the radio frequency signal is realized, loss of the signal is reduced, andstability and reliability of signal transmission are guaranteed further.

Description

Technical field [0001] The invention relates to the field of tile-type active phased array antennas, in particular to a tile-type TR module for vertical transmission of radio frequency signals. Background technique [0002] The TR module is the core component of the active phased array radar. It is located between the antenna and the signal synthesis / decomposition network. The main function is to amplify, shift and attenuate the microwave signal according to the external control signal. In the radar system, each The antenna unit has a TR module corresponding to it. There are thousands or even tens of thousands of TR modules in a radar. The design of the TR module is not only important for reducing the cost, weight and volume of the module, but also for the sensitivity and reliability of the entire radar. Vital. [0003] The existing active phased array antenna TR module mainly includes two types: a vertical integrated horizontal assembly structure based on a brick-type linear sub-...
