Abstract: A radio frequency transceiver includes a container. The container includes a circuit board and the connection assembly. A baseband circuit is disposed on the circuit board. The baseband circuit is configured to synthesize the first baseband signal, and decode the second baseband signal. The connection assembly includes a board-end connector, a cable, and at least one optical module interface. The board-end connector is configured to connect to the baseband circuit. A first end of the cable is configured to connect to the at least one optical module interface, and a second end of the cable is configured to connect to the board-end connector. Each optical module interface of the at least one optical module interface is configured to connect to an external optical module. According to the solutions provided by this radio frequency transceiver, a circuit layout can be more flexible, hardware costs can be reduced, and space can be saved.
