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.

Abstract: A coupler for use in a wireless communication device includes a signal input end, a signal output end, a coupling end, an isolation end, a main signal hole, and a first coupling hole disposed on a PCB. A first end of the main signal hole is coupled to the signal input end. A second end of the main signal hole is coupled to the signal output end. A first end of the first coupling hole is coupled to the coupling end. A second end of the first coupling hole is coupled to the isolation end. In a thickness direction of the PCB, the first end of the first coupling hole and the first end of the main signal hole are close to a first side of the PCB, and the second end of the first coupling hole and the second end of the main signal hole are close to a second side of the PCB.
