| 摘要 |
A radio transceiver circuit (10) for FDD communication is disclosed. It comprises a transmitter (20) for FDD signal transmission in a first frequency band, a first receiver (25) for FDD signal reception in a second frequency band, separate from the first frequency band, and a duplexer (30). An output port (35) of the transmitter (20) is operatively connected to a first port (40) of the duplexer (30) for transmitting, through the duplexer (30), signals in said first frequency band. An input port (45) of the first receiver (25) is operatively connected to a second port (50) of the duplexer (30) for receiving, through the duplexer (30), signals in said second frequency band. The radio transceiver circuit (10) comprises a second receiver (55), separate from the first receiver (25), for reception in said first frequency band. An input port (60) of the second receiver (55) is operatively connected to said first port (40) of the duplexer (30) for receiving, through the duplexer (30), signals in said first frequency band. A related radio communication apparatus is also disclosed. |
