Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings and deficiencies in the prior art, and provide a multi-layer ultra-wideband filter. The ultra-wideband filter is based on an improved high-low pass series equivalent circuit, and cleverly utilizes a three-dimensional space layout to form an ultra-wideband filter. Filter; the passband bandwidth is greatly expanded, thereby realizing the ultra-wideband filtering function and solving the filtering problem at the receiving end of the ultra-wideband antenna

Abstract

The invention relates to the field of microwave communication systems, in particular to a multilayer ceramic ultra-wideband high-pass filter. A multilayer ceramic filter, including an external electrode, an internal electrode, and a plurality of stacked sheet ceramic dielectric layers; the external electrode is composed of a shielded and grounded metal electrode and an input and output metal terminal electrode; The layer plane is coated with internal electrodes, and the internal electrodes include: 2 layers of shielded ground electrodes, 4 strip-shaped lead-out electrodes, and 2 serpentine ground electrodes, among which the strip-shaped lead-out electrodes and the upper and lower sides of the serpentine ground electrodes The input and output coupling capacitors are formed to adjust the bandwidth and cut-off frequency; through the structural optimization of the internal electrodes on different sheet ceramic dielectric layers, filters with different electrical properties can be designed on the same filter volume, and the process efficiency can be effectively improved. Consistency, reliability.

Description

technical field [0001] The invention relates to the field of microwave communication systems, in particular to a multilayer ceramic ultra-wideband high-pass filter. Background technique [0002] With the rapid development of communication technology, people's requirements for wireless communication are not only for simple voice communication, but also for wireless communication systems with large data volume and high security such as high-definition video. Ultra-wideband (UWB) wireless communication technology has become a research hotspot in the field of wireless communication because of its simple system structure, low cost, low power consumption, high transmission rate, and good security. In February 2002, the US Federal Communications Commission (FCC) approved the application of UWB technology in the field of short-distance wireless communication, and opened the frequency band from 3.1GHz to 10.6GHz for commercial use. UWB technology has broad application prospects, suc...
