Abstract
A communication apparatus to support multiband communication is provided. The communication apparatus may be applicable to, for example, a duplexer module for the multiband communication. The communication apparatus may be manufactured to be small and light by simplifying a circuit structure of the duplexer module.
Claims11
A communication apparatus to support a multiband communication, the communication apparatus comprising:
- a transmission signal filtering unit to filter n multiband transmission signals, wherein n denotes a natural number;
- a first path setting unit to transfer one or more of the n multiband transmission signals to an antenna unit;
- a phase shifter to separate the one or more multiband transmission signals and multiband received signals by shifting a phase of the multiband transmission signals transferred to the antenna unit;
- and
- a second path setting unit to connect the phase shifter to n received signal filters.
