Abstract
Description
technical field
[0001] The invention relates to the field of filters, in particular to a folded structure adjustable window dielectric filter. Background technique
[0002] Dielectric filter (English Dielectric filter) is designed and manufactured by using the characteristics of low loss, high dielectric constant, frequency temperature coefficient and thermal expansion coefficient of dielectric ceramic materials, and can withstand high power. It is composed of several long resonators in vertical multi-stage series Or parallel trapezoidal lines. A dielectric filter is a microwave filter that uses a dielectric first resonant cavity to achieve frequency selection through multi-stage coupling.
[0003] At present, dielectric filters have been widely used in communication equipment of wireless base stations and other electronic equipment. The general structure of this dielectric filter includes a first dielectric module, a second dielectric module and a test board. In the exis...
