Abstract: A travelling-wave tube includes an input apparatus, a control circuit, an electron gun, a slow-wave circuit, and an output apparatus. The input apparatus may be configured to receive a radio frequency signal, and feed the radio frequency signal into the slow-wave circuit. The control circuit may be configured to determine a quantity N of electron beams and currents of the N electron beams, and control the electron gun to emit the N electron beams. Further, the slow-wave circuit may perform beam-wave interaction with the N electron beams, to amplify power of the radio frequency signa, and because the slow-wave circuit works in a saturation region, electronic efficiency of the travelling-wave tube can be greater than or equal to a first threshold. The output apparatus may output an amplified radio frequency signal.

Abstract: Example electron gun, vacuum device, and system are provided. An example electron gun includes a cathode, a focus electrode, and an energy exchange module. The energy exchange module includes an anode port, a signal input port, and an energy exchange unit. An input signal is input from the signal input port of the energy exchange module into the energy exchange unit of the energy exchange module, and energy exchange with the input signal is performed by transmitting an electron beam from the anode port of the energy exchange module to the energy exchange unit of the energy exchange module. The electron beam is generated by the cathode, the focus electrode, and the anode port.

Abstract: This application provides a power amplification apparatus, a beamforming system, a transmitter, and a base station. The apparatus includes a power amplifier that amplifies a first signal, a power supply, and a power supply modulator that controls, based on an envelope signal corresponding to the first signal, an operating voltage provided by the power supply to the power amplifier. The apparatus is further configured to amplify a second signal. The first signal is generated based on the part of a target amplified signal whose amplitude falls within a preset amplitude range. The second signal is generated based on the part of the target amplified signal whose amplitude falls beyond the preset amplitude range.

Abstract: A polarization reconfigurable apparatus, a communications device, and a polarization reconfiguration method, the apparatus including a signal generation unit, a signal adjustment unit, a digital-to-analog conversion unit, and a transmission unit that are sequentially connected. A signal transmitted by a first port in the transmission unit is orthogonal to a signal transmitted by a second port in the transmission unit. The signal generation unit is configured to generate a first signal. The signal adjustment unit is configured to determine a polarization mode of a to-be-transmitted signal, divide the first signal into two first signals, and adjust an amplitude and a phase of a 1st first signal and an amplitude and a phase of a 2nd first signal based on the determined polarization mode.
