Abstract

The invention discloses a phased-array antenna subarray power supply circuit and an electric appliance with the power supply circuit. The circuit comprises an input connector, a protection circuit, aninput filter circuit, an input energy storage circuit, a DC converter array circuit, an output energy storage circuit and an output filter circuit. The DC converter array circuit converts a high-voltage electric signal passing through the input energy storage circuit into a low-voltage electric signal; according to the low-voltage electric signal, the output energy storage circuit meets the requirement of the phased-array antenna for instantaneous power in an array plane pulse working state, and the output filter circuit improves the quality of an output signal of the low-voltage electric signal passing through the output energy storage circuit. By means of the mode, after the high-voltage electric signals are converted into the low-voltage electric signals, assemblies on the array face of the phased-array antenna can effectively work, and the size and the weight of the phased-array antenna can be reduced.

Description

technical field [0001] The invention relates to the technical field of phased array antennas, in particular to a phased array antenna sub-array power supply circuit and electrical appliances with the power supply circuit. Background technique [0002] The phased array antenna refers to an antenna that changes the shape of the pattern by controlling the feeding phase of the radiating elements in the array antenna. Controlling the phase can change the direction of the maximum value of the antenna pattern to achieve the purpose of beam scanning. [0003] In order to increase the detection distance and power of the antenna, an effective means is to expand the array element size of the phased array antenna. The ensuing problem is that the demand for power supply is greatly increased. In order to reduce the power loss of the power supply transmission cable , the usual solution is to increase the transmission voltage sent to the phased array antenna face. [0004] Most of the dev...
