Abstract

The invention discloses communication equipment and a filter thereof. The filter comprises a shell provided with a first direction and a second direction perpendicular to the first direction; a first filtering branch arranged on the shell and composed of eight filtering cavities which are sequentially coupled, wherein the eight filtering cavities of the first filtering branch comprise two capacitive cross coupling zero points; and a second filtering branch, wherein the second filtering branch and the first filtering branch are sequentially arranged in the first direction, the second filtering branch is composed of seven filtering cavities which are sequentially coupled, the seven filtering cavities of the second filtering branch comprise two capacitive cross coupling zero points, and the first filtering branch and the second filtering branch are divided into four columns arranged along the first direction. By means of the mode, the filter is provided, the multiple filtering cavities are regularly arranged in the shell to form four rows, the coupling zero points are arranged, the containing space of the filter can be reduced, zero point suppression can be achieved, and index debugging is facilitated.

Description

technical field [0001] The present application relates to the technical field of communication, in particular to a communication device and a filter thereof. Background technique [0002] In the mobile communication system, the required signal is modulated to form a modulated signal, which is carried on a high-frequency carrier signal, transmitted to the air through the transmitting antenna, and the signal in the air is received through the receiving antenna. Among the signals received by the receiving antenna, not only Include the desired signal, but also include other frequency harmonics, noise signals. For the signal received by the receiving antenna, it is necessary to use a filter to filter out unnecessary harmonics and noise signals. Therefore, the designed filter must precisely control its bandwidth. [0003] The inventors of the present application have discovered during long-term research and development work that the arrangement of multiple filter cavities in the...
