The invention belongs to frequency conversion technology and relates to a frequency conversion component structure. The frequency conversion structural component of the present invention adopts a three-layer installation structure of A layer, A-B interlayer, and B layer. Among them, there are functional circuit boards with different frequency bands on layer A and layer B respectively, and the functional circuit boards on the same layer are physically isolated, and the signal interaction between them is connected through highly shielded thin coaxial cables; The signal interaction between the functional circuit boards on the layer is connected through the signal connecting columns arranged on the A-B interlayer. And through the power adapter board I, the power adapter board II and the feedthrough capacitor, the power supply problem of each functional circuit board that needs efficient isolation is solved. The present invention effectively reduces the volume of the frequency conversion component structure through the high integration of various functional circuit boards, optimizes the layout of the functional circuits of the frequency conversion component in a limited space, completes efficient isolation between circuits, and greatly reduces signal lines. , The crosstalk that is easily introduced by the power line connection has great practical application value.
Description
Frequency conversion component structure technical field [0001] The present invention belongs to frequency conversion technology, and relates to a frequency conversion component structure. Background technique The frequency conversion assembly that adopts in the development of a certain type of guided gliding bomb is used for carrying out frequency conversion processing input to 4 road GPS signals The intermediate frequency signal is processed by the anti-jamming algorithm, and the processed intermediate frequency signal fed back is restored to the RF GPS signal No. Due to the complex functional composition of frequency conversion components, there are many power supply, up and down frequency conversion, intermediate frequency, power division and local oscillator circuits, and some circuits There are obvious frequency band differences between the signals, which are very easy to interfere with each other. At the same time, the installation space on the projectile is very...
