The invention discloses a generation device and method for a wide-range reconfigurable UWB (Ultra-Wideband) based on cascaded DE-MZMs (Dual-Electrode Mach-Zehnder Modulators), belongs to the technical field of the ultra-wide band and aims at generating any first-order to fifth-order UWB signals and realizing adjustable pulse polarity, under the condition of not changing a system structure. The device comprises a laser, an optical coupler, a first-level DE-MZM, a second-level DE-MZM, a Gaussian pulse signal generator, a first photoelectric detector, a second photoelectric detector and an amplifier. The laser is connected with the optical coupler. According to the method, the continuous light generated by the laser passes through the optical coupler and then is divided into two ways; Gaussian pulse signals are attenuated and delayed and then are respectively input into two arms of the first-level DE-MZM; the signals at two arms of the first-level DE-MZM are converted into electric pulses by the first photoelectric detector; the signals are amplified, attenuated and delayed by the amplifier and then are input into the two arms of the second-level DE-MZM for secondary modulation; and after the modulation, the signals are output.
