Problems solved by technology

[0009] Therefore, using the above-mentioned traditional multi-layer technology, only the embedded signal traces can be used to improve the compactness of the circuit module, which cannot significantly and effectively save the area or volume occupied by the passive components in the product.
And in a wireless communication system, based on characteristic considerations, the external antenna elements need to consider the relative position of the integration, which wastes the integration area of ​​many modules

Embodiment Construction

[0088] See first Figure 4 , Figure 4 An embodiment of the systematic multi-layer circuit module integrated design method of the present invention is described. The structure of the circuit module includes a multi-layer ceramic substrate (Multi-LayerCeramic) constructed by Low Temperature Co-fired Ceramic technology. ). These multi-layer structures can be divided into several integration areas according to the passive components used in the actual circuit.

[0089] These integration areas include internal wiring integration areas, basic passive component integration areas and high-frequency passive component integration areas. The wiring integration areas include connection layers, and the basic passive component integration areas can be subdivided into capacitor layers, resistor layers, and inductors. Floor. The high-frequency passive component integration area is reserved for high-frequency passive components, including filters, couplers, balanced and unbalanced impedanc...
