Abstract

The present application discloses a combiner and a communication device. The combiner includes: a casing, a first filtering branch and a second filtering branch, the casing is formed with a first cavity and a second cavity, and the first filtering branch includes seven filtering branches arranged in the first cavity filter cavity, seven filter cavities are coupled in sequence, and the third filter cavity and the fifth filter cavity in the seven filter cavities are capacitively cross-coupled to achieve zero-point suppression, and the first filter branch has only one capacitive crossover Coupling, high material consistency, easy to process and manufacture. The second filtering branch includes a connecting strip and eleven branches arranged in the second cavity, the connecting strip is connected with the eleven branches, and the eleven branches are arranged at intervals. Therefore, the combiner of the present application uses the connecting strip and the branch to cooperate to form the second filter branch and the first filter branch formed by the filter cavity to form a combiner, so as to reduce the number of welding points of the combiner and reduce the The volume of the combiner reduces the production cost.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a combiner and a communication device. Background technique [0002] In the mobile communication system, the required signal is modulated to form a modulated signal, which is mounted on a high-frequency carrier signal, transmitted to the air through the transmitting antenna, and received by the receiving antenna in the air. In the signal received by the receiving antenna, not only Including the desired signal, but also other frequency harmonics, noise signals. For the signal received by the receiving antenna, a combiner needs to be used to filter out unwanted harmonics and noise signals. Therefore, the designed combiner must precisely control its bandwidth. [0003] The inventor of the present application found in the long-term research and development work that each filter branch in the current combiner composed of two filter branches is formed by arran...
