The invention relates to a smart microwave combined pulse generator which comprises a time sequence combined pulse generation branch and a frequency combined pulse branch. The time sequence combined pulse generation branch comprises double input ports, a PIN amplitude limiter, a proportion adjustment attenuator, a PIN pulse modulator, a power divider / combiner, a low noise amplifier, an isolator and an output port. The frequency combination pulse branch comprises double input ports, a PIN amplitude limiter, a power divider / combiner, a PIN pulse modulator, a low noise amplifier, an isolator andan output port. The technical problems that an existing microwave pulse generation mode is single, the frequency band is limited, connection is complex, and stability is poor are solved. The pulse width of an external driving signal is adjusted through the PIN pulse modulator, and a pulse signal with the corresponding width can be generated; The delay time of the used external driving pulse signalis adjusted, and a time sequence corresponding to the interval time can be generated; Different power ratios can be obtained by adjusting the attenuator according to the proportion, and the method issuitable for simulating application occasions where various microwave waveforms are generated.
Description
technical field [0001] The invention relates to a smart microwave combined pulse generator, in particular to a device which utilizes microwave devices to generate multiple pulse patterns. Background technique [0002] Generating microwave pulses in various styles is the basis for microwave measurement and effect research. Several typical multi-style microwave pulse generation methods: [0003] The first generation method is to directly use the pulse modulation method of the standard microwave signal source. The amplitude of the continuous wave output by the standard microwave signal source is stable, which can be used as a high-quality pre-stage signal source and excitation signal source. The main disadvantages are: the pulse pattern is relatively simple, and the main parameters are pulse width and pulse repetition frequency (or pulse repetition period). The form of narrow pulse output is simple, the minimum single pulse width is limited to 10ns (the low band is limited t...
