The invention puts forward a control protection module for a microwave power module. The control protection module comprises a pulse detection unit and a pulse generation unit, wherein the pulse detection unit is used for identifying pulse width and repeated frequency of input pulse signals, protection enable signals are sent out according to requirements of travelling wave tube operating characteristics, modulator pulses and solid state power amplifier pulses that are nested within each other are generated via the pulse generation unit according to the input pulse signals and are respectively used as input pulse signals for a modulator and a solid state power amplifier, and whether to output the modulator pulses and the solid state power amplifier pulses that are nested within each other to the modulator and the solid state power amplifier is determined via the pulse generation unit according to the protection enable signals. The control protection module can help prevent sparking phenomena caused by incorrect pulse signals from occurring in a travelling wave tube, and detection waveform indexes output via the travelling wave tube can be raised.
Description
technical field [0001] The invention belongs to the technical field of radar, and in particular relates to a control and protection module which can be commonly used in electric vacuum amplifiers and solid-state amplifiers. Background technique [0002] The control and protection module for microwave power module (MPM) is a control and protection module specially used for MPM. In the MPM, the high power amplifier adopts the traveling wave tube scheme. Since the traveling wave tube uses the pulse working mode, the pulse signal of the floating modulator controlling the working of the traveling wave tube is given through the control and protection module. Therefore, whether the traveling wave tube can work normally is closely related to the detection and generation of the pulse signal by the control protection module. [0003] The existing control and protection module includes many units, such as power supply unit, control unit, pulse unit, etc., and the pulse unit is related...
