Abstract

The invention discloses a centimeter wave / millimeter wave ultra-wideband signal generation device based on combination of a microwave photon external modulation technology and an up-conversion technology, and belongs to the technical field of microwave photonics. The device comprises a laser source, a coupler 1, a coupler 2, a polarization controller 1, a polarization controller 2, a double-parallel Mach-Zehnder modulator, a Mach-Zehnder modulator, an arbitrary waveform generator, a microwave signal source, a direct-current voltage-stabilizing source 1, a direct-current voltage-stabilizing source 2, a direct-current voltage-stabilizing source 3, a direct-current voltage-stabilizing source 4, an erbium-doped optical fiber amplifier, an adjustable optical filter, an adjustable optical delay line, a balanced photoelectric detector, a spectrum analyzer and an oscilloscope. The device can generate centimeter-wave ultra-wideband signals and millimeter-wave ultra-wideband signals, and is suitable for an indoor ultra-wideband communication system and an outdoor ultra-wideband radar system. Compared with other methods, the method for realizing the up-conversion technology based on single side band modulation has better flexibility and stability, and is more suitable for transmission of ultra-wideband signals in long-distance optical fibers.

Description

technical field [0001] The invention belongs to the technical field of microwave photonics, and in particular relates to a centimeter-wave / millimeter-wave ultra-wideband signal generating device based on microwave photon external modulation technology combined with up-conversion technology. Background technique [0002] UWB radio frequency technology is a short-distance wireless transmission technology that has the advantages of high speed, low intercept probability, anti-multipath fading, anti-jamming, and low power consumption. The Federal Communications Commission of the United States has allocated the centimeter-wave frequency band of 3.1-10.6 GHz for indoor ultra-wideband communication systems, and the millimeter-wave frequency band of 22-29 GHz for outdoor ultra-wideband radar systems, and limited the power spectral density of ultra-wideband signals to -41.3 Below GHz / MHz, this limitation is also called UWB mask, so the wireless propagation distance of UWB signals is l...
