Abstract

The invention discloses communication equipment and a filter thereof. The filter comprises: a shell having a first direction and a second direction perpendicular to each other; a first port, wherein a first filtering branch and a second filtering branch are respectively coupled with the first port, and are arranged on the shell; the first filtering branch composed of seven filtering cavities which are coupled in sequence, wherein the seven filtering cavities of the first filtering branch further form three cross coupling zero points; and the second filtering branch composed of seven filtering cavities which are coupled in sequence, wherein the seven filtering cavities of the second filtering branch further form three inductive cross coupling zero points. Through the above mode, the arrangement of the common port can reduce the number of taps, reduce the size of the filter, realize zero suppression through pure inductive cross coupling zero, facilitate index debugging, have good material consistency, and reduce the product complexity.

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 mobile communication equipment, the required signal is modulated to form a modulated signal, which is loaded 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 found in long-term research and development work that in order to reduce the volume of the filter, the filter is usually...
