Abstract

The invention discloses a multi-channel tile-type phased-array transceiver array and a manufacturing method thereof, and belongs to the technical field of phased arrays. The array of the invention comprises a sub-array module layer, a heat dissipation layer and a functional circuit layer, and the sub-array module layer comprises a sub-array module. The sub-array module comprises an upper metal shell and a lower metal shell, wherein a closed cavity is formed between the upper metal shell and the lower metal shell. The upper surface of the upper metal shell is provided with an antenna circuit board, and a lower surface of the upper metal shell is provided with a transceiver circuit board. A power distribution / synthesis network and a power supply control interface are disposed on the transceiver circuit board. The lower metal shell is provided with a second RF connector and a low-frequency connector, and the low-frequency connector is mutually connected with the power control interface. The array has the advantages of good heat dissipation and airtightness, high degree of integration, small size, light weight and convenient use, can effectively reduce the profile height of the array,and is beneficial to realize integration and miniaturization of the array.

Description

technical field [0001] The invention relates to the technical field of phased arrays, in particular to a multi-channel tile-type phased array transceiver array and a manufacturing method thereof. Background technique [0002] The development of phased array technology has promoted the further development of radar technology. Phased array radar has the advantages of good flexibility and fast beam scanning. Compared with the traditional mechanical scanning radar, the phased array radar can realize the rapid scanning of the beam by controlling the amplitude and phase of the array elements. In view of the superiority of phased array technology, more and more measurement and control and communication scenarios adopt the phased array system. [0003] Usually, a phased array array has multiple channels. As the number of channels increases, the entire phased array product becomes very large, even exceeding the acceptable volume requirements of the entire system, thus limiting the ...
