[0004] The purpose of the present invention is to overcome the wave control distribution board used in the existing wave control system, resulting in a rigid connection between the wave control distribution board and the one-to-one cable and the wave control sub-board of the TR module, resulting in excessive requirements for welding, and It is difficult to guarantee the requirements, so the present invention provides an active phase control that uses a one-point multi-wave control forming cable instead of a wave control distribution board and a one-to-one cable to realize the normal transmission of wave control commands.

The invention relates to a wave controlling system of an active phased-array antenna. The wave controlling system comprises a wave controlling bus, a TR module wave controlling sub-plate, and a wave controlling molding cable. The wave controlling bus is used for receiving wave controlling instructions sent by the back end of an antenna. The TR module wave controlling sub-plate is used for receiving the wave controlling instructions, thereby achieving the wave controlling function for a TR module. The wave controlling molding cable is connected with the wave controlling bus and the TR module wave controlling sub-plate, and is used for transmitting the wave controlling instructions sent by the wave controlling bus to the TR module wave controlling sub-plate.
Description
technical field [0001] The invention relates to an active phased array antenna, in particular to an active phased array antenna wave control system. Background technique [0002] At present, the structure of the wave control system of the front-end product of the active phased array antenna is usually divided into three parts: the wave control sub-board of the TR module, the wave control distribution board, and the wave control motherboard. The wave control motherboard receives the wave control commands sent from the back end of the antenna, and after the FPGA on the wave control motherboard solves them, it distributes them to the wave control distribution board through 4 one-to-one cables connected to the wave control distribution board. The wave control distribution board is distributed to the wave control sub-board of the TR module through the connector on the board to realize various control functions of the TR module. [0003] Such as figure 2 The structure of the wav...
