Description

Technical Field

[0001] This invention relates to an equal-phase integrated interconnect module. Background Technology

[0002] The phased array radar antenna array is the core component of a radar. To meet the requirements of system flexibility and openness, the new generation of active phased arrays has evolved from traditional single-module combinations to highly integrated, multi-modular designs. The active subarray system, as the core module within the antenna array, can expand or reduce the aperture of the array antenna according to functional needs.

[0003] An active subarray system includes array elements, T / R module, power divider network module, secondary power supply module, driver module, delay line module, digital receiver module, subarray skeleton, and interconnection interfaces between modules within the subarray. Common active subarray structures include two-dimensional integrated brick type, one-dimensional integrated blade type, and stacked integrated tile type.

[0004] For active subarray systems that make up large-aperture array antennas, the element spacing and number of elements are large, and the T / R module and other modules are highly concentrated, resulting in a large lateral span between the active subarray surface and the T / R module. At the same time, to reduce system communication losses, the vertical distance is required to be very small. Therefore, the interconnection space between large-scale elements and multi-channel T / R module is extremely limited. In the case of multi-channel interconnection and high-frequency, high-power transmission, it is difficult to achieve a high-density, equiphase, and orderly arrangement of RF signal channels in a limited space using ordinary RF component connection methods. Even if additional space is added, disassembly, assembly, and maintenance are extremely complex. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an equal-phase integrated interconnect module to solve the problem of wiring difficulties of the radio frequency cable assembly within the module when installing interconnects in a concentrated area at the end of a large-diameter array.
