Apparatus for generating digital ultra-wideband pulse with adjustable pulse width

The invention discloses a digital type ultra wideband impulse generating device with adjusted impulse width, which comprises a digital information source module, a level conversion and clock distribution module, a delay control module, an impulse generating module, a differentiating circuit module and a low noise wideband power amplification module, which are orderly connected in series. The digital information source module generates a clock signal with periodic TTL level, the clock signal is converted and distributed into three channels of clock signals with ECL level by the level conversion and clock distribution module, the delay control module adjusts the delay differences of the three channels of clock signals with ECL level, the signals undergoing different delays are sent to the impulse generating module to generate an extremely narrow impulse, and the extremely narrow impulse passes through the differentiating circuit module and the low noise wideband power amplification module to output an ultra wideband impulse signal. The device has the characteristics of simple circuit and easy integration.
