description A radio frequency module includes: a first antenna connection terminal; a second antenna connection terminal different from the first antenna connection terminal; a first filter having a passband of a first frequency range including a first communication band allocated as a TDD communication band; a second filter having a passband of a second frequency range including a second communication band allocated as a TDD communication band; and a third filter having a passband of a third frequency range including a third communication band allocated as a TDD communication band. The third frequency range is located between the first frequency range and the second frequency range. The first and second filters are both connected to one of the first antenna connection terminal and the second antenna connection terminal. The third filter is connected to the other of the first antenna connection terminal and the second antenna connection terminal.
