The power supply network 4 includes: a subarray blind-plug power supply assembly 4-1, a power supply copper bar 4-2, and a power supply terminal 4-3. The subarray blind-plug power supply assembly 4-1 is sequentially installed on the upper end face of the mounting structure assembly 5 according to the power supply port positions of the array subarrays. The power supply copper bar 4-2 is first fixed to the insulating plate 6 and then uniformly fixed to the other side of the mounting structure assembly 5. The power supply terminal 4-3 is sequentially installed on the power supply copper bar 4-2, and the power supply cable is then connected to the different power supply copper bars according to the power supply requirements of the subarray. In the power supply network of this embodiment, the power supply copper bar and power supply cable are connected using terminals and installed on a highly heat-resistant polyimide insulating board. This can provide high-current power supply to the digital array antenna subarrays, improving safety.

[0036] In this embodiment, the transmission network, local oscillator network, dual local oscillator network, reference clock network, and sampling clock network are all composed of blind-plug 1-to-2 power splitters, equal-power RF power splitters, and semi-steel cables for the corresponding frequency bands. Blind-plug 1-to-2 power splitters and equal-power RF power splitters in the same frequency band are connected via semi-steel cables. Blind-plug 1-to-2 power splitters and equal-power RF power splitters are divided into power splitters for different frequency bands based on the different microwave signal requirements of the digital array antenna subarrays.

The semi-steel cables in the transmission network, local oscillator network, second local oscillator network, reference clock network, and sampling clock network are designed and laid out with equal phases based on the corresponding positions of blind-plug 1-to-2 power splitters and equal-power RF power splitters with the same function.

Each of the blind-plug 1-to-2 power splitters in the subarray blind-plug RF assembly 2 is assembled sequentially based on the location of the subarray input ports and assembled between the upper mounting plate 2-2 and the lower mounting plate 2-8 using screws 2-1. The subarray feed ports all use blind-plug SBMA RF connectors, while the main port uses an SSMA RF connector.
