Abstract

The invention discloses a high-power tile type phased-array antenna, comprising a first printed circuit board layer, a second printed circuit board layer and a third printed circuit board layer whichare arranged in sequence. The first printed circuit board layer is used for transmitting radio frequency signals and realizing a 64-unit power division network. The second printed circuit board layeris electrically connected with the first printed circuit board layer and is used for controlling phase shift and attenuation of signals. The third printed circuit board layer is electrically connectedwith the second printed circuit board layer and is used for power supply and signal input control. A plurality of chips for signal output are arranged on the first printed circuit board layer. A heatdissipation cold plate is arranged between the second printed circuit board layer and the third printed circuit board layer, and the heat absorption end of the heat dissipation cold plate is in contact with the chips. According to the invention, the problem of chip heating in the antenna can be solved in real time, and high-power transmission of signals can be truly realized.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a high-power tile-type phased array antenna. Background technique [0002] Traditional radar phased array antennas mainly use brick-type T / R components or tile-type T / R components. The traditional brick-type integration method mainly refers to: T / R components adopt vertical layout and horizontal assembly integration form; The tile-type integration method mainly refers to: T / R components adopt the integration form of horizontal layout, vertical assembly, and vertical interconnection. [0003] The traditional brick-type antenna has a large vertical size, heavy weight, low integration, and high requirements on the scale of the feed network, while the tile-type antenna has a series of high-density integration, low profile, light weight, and low mass production cost. advantages, so that a large number of applications can be obtained. [0004] However, the current tile-type ph...
