Abstract: An example remote radio apparatus is provided, including a body, a mainboard, a mainboard heat sink, a maintenance cavity, an optical module, and an optical module heat sink. The maintenance cavity and the optical module heat sink are integrally connected, while the optical module is mounted on a bottom surface of the optical module heat sink. The maintenance cavity and the optical module heat sink are mounted on a side surface of the body, and the mainboard heat sink is mounted on and covers the mainboard. The mainboard heat sink and the mainboard are installed on a front surface of the body, and the mainboard heat sink and the optical module heat sink are spaced by a preset distance. The temperature of the optical module is controlled within a range required by a specification.

Abstract: Embodiments of the present disclosure disclose a radio remote unit, a receiver, and a base station. The radio remote unit includes at least one receive channel pair, a first local oscillator module, a second local oscillator module, a local oscillator switching switch, and a controller. Each receive channel pair includes a first receive channel and a second receive channel. Each receive channel in each receive channel pair includes a filtering module, a frequency mixing module connected to the filtering module, and a digital processing module connected to the frequency mixing module. A frequency mixing module on the second receive channel is connected to the first local oscillator module and the second local oscillator module by the local oscillator switching switch. The controller is configured to receive an operating mode that is sent by a base station, and control the local oscillator switching switch to perform switching.

Abstract: Example access network devices are described. One example access network device includes a signal processing apparatus. The signal processing apparatus includes a first power amplifier, a second power amplifier, a first filter, a second filter, and a combiner. The first filter filters a second signal obtained by the first power amplifier, to obtain a first sub-signal belonging to a first frequency band and a second sub-signal belonging to a second frequency band. The second filter filters a fourth signal obtained by the second power amplifier, to obtain n sub-signals including at least a third sub-signal belonging to a third frequency band. The combiner combines the first sub-signal and i sub-signals in the n sub-signals based on a preset condition, to obtain a first combined signal. The communication module sends the first combined signal by using a first port, and sends the second sub-signal by using a second port.
