Abstract

The invention discloses a filter, communication equipment, a method for preparing a dielectric block and a method for preparing a filter. The filter comprises a dielectric block which is provided withN cascaded hollow resonant cavities, and a first window is arranged between the two cascaded hollow resonant cavities, wherein N is a natural number greater than 1, and materials of the filter at least comprise zinc oxide, silicon dioxide and magnesium oxide. By means of the mode, far-end out-of-band rejection can be greatly improved, clutters are pushed to a higher frequency, near-frequency-bandinterference is reduced, and the stability of the performance of the filter is improved; and the filter has a low dielectric constant, low loss and a near-zero temperature coefficient, so that the dielectric property of the filter can be improved.

Description

technical field [0001] The present application relates to the field of communication technology, in particular to a filter applied to a 5G communication system, a communication device, a method for preparing a dielectric block and a filter. Background technique [0002] With the rapid development of communication technology, especially the upcoming 5G communication era, more stringent technical requirements are put forward for the system architecture. In order to achieve high-efficiency and large-capacity communication, the system modules must be highly integrated, miniaturized, Lightweight and low cost, such as 5G Massive MIMO technology, in order to further expand the system channel from the current 8 or 16 channels to 32, 64 or 128 channels, at the same time, the size of the overall system architecture should not be too large, and even a certain degree of The miniaturization of the microwave filter is the core component of the system, and its performance parameters, size,...
