Abstract

The invention provides a microwave digital power supply composite substrate circuit based on a sandwich structure and a feeder device. The microwave digital power supply composite substrate circuit ischaracterized in that the sandwich structure adopts a three-layer structure, namely a control circuit printing board, a microwave strip line and a power supply circuit printing board; the input end of a final-stage wave control circuit is connected with a photoelectric conversion module for input through optical fibers, and an access control signal and serial control data are allocated to each ofbranches of the microwave digital power supply composite substrate circuit for output; a double-sided vertical interconnection power division network adopts the design of integration of a linear power distribution network with a resistive film and double-sided vertical interconnection transformation; a final-stage power supply conversion circuit converts input voltage into multiple DC voltages for output, and instantaneous power output is provided for a final-stage active circuit. According to the sandwich structure, the complete composite substrate circuit is mixed and integrated, so that the space and weight requirements of an active phased array sub-array module can be greatly reduced, and the array surface light miniaturization is realized.

Description

technical field [0001] The invention relates to the technical field of active electronically scanned array radar, in particular to a microwave digital power composite substrate circuit and a feeder device based on a sandwich structure. Background technique [0002] Active phased array radar is currently the most mainstream form of radar. Its core connotation is to realize the wide bandwidth angle fast scanning of the antenna array beam, low sidelobe, and anti-interference by individually controlling the amplitude and phase of each active transceiver channel of the antenna array. and many other advantages, generally use row / column active sub-array modules to integrate the array in a brick-like manner. [0003] At present, the common design method for the feeder design of active phased array radar is to independently design the column sub-array or row sub-array power division / synthesis network, the final wave control circuit and the final power supply circuit, and configure th...
