Abstract
The invention provides a radio frequency impedance network and a making method thereof, applicable to the field of electronic elements. In the radio frequency impedance network, n coils are combined side by side, every coil is independent, the magnetic force line of each coil is closed, the n coils are in a symmetrical structure, magnetic circuits of two coils at the edges in the n coils are identical, and n can be an integer not smaller than 2. In the radio frequency impedance network, based on the principle of electromagnetic compatibility, by adopting an LTCC (Low Temperature Co-Fired Ceramic) technology and a laminated printing technology, a plurality of inductance coils are integrated in one chip through the cofiring and patterning of multi-layer multi-component ceramic, and every inductance coil is an independent inductance coil with a closed magnetic force line. The invention can solve the problem of electromagnetic interference and coupling among elements to a certain degree, is beneficial to miniaturization of a complete machine, is convenient to integrate, has high anti-electromagnetic interference capability and improves the comprehensive performance of the complete machine.
Description
technical field [0001] The invention belongs to the field of electronic components, in particular to a radio frequency impedance network and a manufacturing method thereof. Background technique [0002] Due to the continuous development of communications, computers and their peripheral products, and household appliances in the direction of high frequency, digitalization, and miniaturization, the requirements for miniaturization, integration, and modularization of components are becoming more and more urgent. For small components with strong anti-interference Device requirements are becoming more and more urgent. In order to adapt to the trend of miniaturization and integration, and to meet the needs of multiple lines to suppress noise, and to further improve the installation efficiency and installation density, the radio frequency impedance network came into being, and with its excellent electrical performance characteristics and excellent electromagnetic interference ( Ele...
