Abstract

The invention discloses communication equipment and a filter thereof. The filter comprises a first common cavity arranged on a first surface of a shell, a second common cavity arranged on a second surface of the shell, a first filtering branch arranged on the first surface and coupled with the first common cavity, a second filtering branch arranged on the first surface and coupled with the first common cavity, a third filtering branch arranged on the second surface and coupled with the second common cavity, a fourth filtering branch arranged on the second surface and coupled with the second common cavity, and a fifth filtering branch arranged on the second surface and coupled with the second common cavity. Through the mode, the number of taps can be reduced through the arrangement of the common cavity, and the size of the filter is reduced; the front and back arrangement reduces the size of the filter and reduces the cost.

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 have discovered in long-term research and development work that each existing filter branch needs to be independently pr...
