Communication apparatus

A communication apparatus, comprising a first filter, a second filter, and a common resonant cavity;

• wherein
• the first filter and the second filter are configured to filter a radio frequency signal;
• the first filter comprises at least one resonant cavity;
• the second filter comprises at least one resonant cavity;
• the common resonant cavity is located between a 1st resonant cavity of the first filter and a 1st resonant cavity of the second filter, and the common resonant cavity is connected to the 1st resonant cavity of the first filter and the 1st resonant cavity of the second filter;
• and
• the common resonant cavity is configured to isolate the first filter from the second filter, or couple the first filter to the second filter, wherein if the first filter is isolated from the second filter, the communication apparatus is in an operating status of a pass-through state;
• and if the first filter is coupled to the second filter, the communication apparatus is in an operating status of a power division state.

A communication apparatus, comprising a first filter, a second filter, and a ground control assembly;

• wherein
• the first filter and the second filter are configured to filter a radio frequency signal;
• the first filter comprises at least one resonant cavity, the second filter comprises at least one resonant cavity, and the ground control assembly is connected to the 1st resonant cavity of the second filter;
• and
• the ground control assembly is configured to control whether the 1st resonant cavity of the second filter is grounded, wherein if the 1st resonant cavity of the second filter is not grounded, the communication apparatus is in an operating status of a power division state;
• and if the 1st resonant cavity of the second filter is grounded, the communication apparatus is in an operating status of a pass-through state.
