Embodiment Construction
[0034] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

The invention discloses a resonator with a liner resonance rod. The resonator comprises a resonance cavity, the resonance rod and a turning screw, wherein the resonance cavity is connected with the resonance rod and the turning screw, the resonance cavity comprises two side walls, an upper top wall and a lower bottom wall, the inner side of the lower bottom wall and / or the inner side of the upper top wall are / is connected with one end surface of the resonance rod, in addition, the lower bottom wall and / or the upper top wall are / is provided with through holes allowing the turning screw to pass, the two side walls are connected with the upper top wall and the lower bottom wall, the resonance cavity with the hollow inside is formed, the resonance rod is arranged in the resonance cavity and is in a shape of at least one rectangular square wave, the outer side surface of one short edge in the resonance rod is connected with the inner side wall of the lower bottom wall of the resonance cavity and / or the inner side surface of the upper top wall, and the turning screw is connected with the upper top wall in the resonance cavity and / or the lower bottom wall, is in arrangement of being crossed with the resonance rod and is arranged in the resonance cavity in a disconnected way. The resonator solves the problem that the shape of the resonator is too large, or the too low quality factor avoidance cannot be ensured after the shape reduction.
Description
technical field [0001] The invention relates to the field of resonators, in particular to a resonator with a linear resonant rod. Background technique [0002] In the prior art, with the rapid development of communication systems, people have increasingly strict requirements on communication equipment, and miniaturization and high performance have become the main direction for equipment manufacturers to pursue for devices. Among them, the resonator is a widely used network element, which has the characteristics of energy storage and frequency selection, and can be applied to many microwave passive devices such as filters, duplexers and oscillators. [0003] For resonators, two resonating rods have been used to reduce the resonant frequency until now: [0004] (1) if figure 1 As shown, it is a resonant rod with a disk, which reduces the resonance frequency by increasing the size of the disk. Therefore, the resonator made of a resonant rod with a disk inevitably increases th...
