The large-amplitude high repetition frequency nanosecond balance pulse signal generator includes a unipolarity pulse signal generation circuit and a balance pulse generation circuit, wherein the unipolarity pulse signal generation circuit includes a triode pulse generation circuit which is formed by triodes; each triode includes two cascades, has a cascaded connection design, and has avalanche effect; the unipolarity pulse signal generation circuit is used for generating a large-amplitude high repetition frequency nanosecond negative pulse signal, started by the input bipolarity start pulse signal; the front end of the balance pulse generation circuit is electrically connected with the unipolarity pulse signal generation circuit; and the balance pulse generation circuit is used for converting the large-amplitude high repetition frequency nanosecond negative pulse signal into a balance pulse signal, and generating a large-amplitude nanosecond balance pulse signal. The large-amplitude high repetition frequency nanosecond balance pulse signal generator has the advantages of being novel in design, being simple in the circuit structure, being high in the waveform symmetry of the generated nanosecond balance pulse signal, being low in the ringing level, being high in amplitude, and being high in repetition frequency, and being able to be applied to a pulse ultra wide band radar system to guarantee greater detection distance and good detection performance.

Description

technical field [0001] The invention belongs to the technical field of electronic components in the electronics industry, and in particular relates to a nanosecond balanced pulse signal generator with large amplitude and high repetition frequency. Background technique [0002] UWB technology uses nanosecond or picosecond impulse pulses as carriers to transmit information. It has the advantages of high bandwidth, low power consumption, strong anti-multipath fading ability, and good concealment performance. It can be widely used in radio communications, ultra- Broadband radar system detection, positioning and tracking and other fields. In order to achieve a large distance detection, the transmitted pulse signal is required to have a large instantaneous power, that is, a large pulse amplitude is required. At the same time, in order to meet the ultra-wideband detection requirements, a narrow pulse width and a high repetition frequency are required. Therefore, how to generate a l...

Problems solved by technology

[0003] In the prior art, conventional cmos devices are used to design and generate pulse signals. This pulse signal output method has the following disadvantages: the output pulse amplitude is low, and the repetition frequency of the output pulse signal is usually not high due to the limitation of the device. Therefore, it is difficult to meet the super Practical Detection Application Requirements for Wideband Radar Systems
