Radio-frequency front-end circuit and communication apparatus

A radio-frequency front-end circuit comprising:

• an antenna terminal;
• a transmit filter configured to pass a transmit signal of a time division duplexing (TDD) band;
• a receive filter configured to pass a receive signal of the TDD band;
• a filter configured to pass a radio frequency signal of a frequency division duplexing (FDD) band;
• and
• a switch configured to switch a connection between the antenna terminal and the transmit filter, a connection between the antenna terminal and the receive filter, and a connection between the antenna terminal and the filter, and to simultaneously connect the antenna terminal to the transmit filter and to the filter, and to simultaneously connect the antenna terminal to the receive filter and to the filter,
• wherein a phase difference between a phase of the radio frequency signal of the FDD band in response to the switch simultaneously connecting the antenna terminal to the transmit filter and to the filter, and a phase of the radio frequency signal of the FDD band in response to the switch simultaneously connecting the antenna terminal to the receive filter and to the filter, is 10 degrees or less.
