Embodiment Construction

[0053] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0054] In view of the problem that the existing frequency doubling scheme uses an optical filter to select the required harmonic frequency, the complexity of the system is increased, and the tuning speed and adjustable range of the frequency are limited. The invention generates a twelvefold frequency electrical signal after the beat frequency demodulation of the photoelectric detector; the optical sideband suppression ratio (OSSR) is 30.6dBm, and the radio frequency sideband suppression ratio is 36.05dBm.

[0055] The application principle of the present invention will be described in detail below in conjunction with the ac...

Abstract

The invention belongs to the technical field of wireless communication and spatial communication, and discloses a DP-MZM-based novel twelve-frequency multiplication millimeter wave generation device and method. A laser is connected with the double-parallel Mach-Zehnder modulator through a polarization controller, and the radio frequency signal source is connected with the double-parallel Mach-Zehnder modulator. The double-parallel Mach-Zehnder modulator is connected with Aphotoelectric detector through the polarization controller. According to the invention, 5GHz and 20GHz radio frequency local oscillator signals are taken, the frequency multiplication system successfully generates 60GHz and 240GHz high frequency microwave signals, and the scheme has flexible tunability; factors influencing OSSR and RFSSR are analyzed, and the feasibility of the scheme is proved. Compared with the conventional frequency multiplication scheme, the optical millimeter wave signal with higher frequency canbe generated under the condition that filtering is not needed..

Description

technical field [0001] The invention belongs to the technical field of wireless communication and space communication, and in particular relates to a novel 12-fold frequency millimeter wave generation device and method based on DP-MZM. Background technique [0002] At present, in recent years, there is an increasing demand for high-speed data rate services, but it cannot be supported by existing crowded frequency bands. In order to overcome spectrum congestion and support future business needs, a method of using the millimeter wave (MM) frequency band is proposed. The MM frequency band from 30 to 300GHz provides a huge bandwidth (BW) of about 270GHz. Due to the rich BW, it can provide long-distance and super-capacity business requirements for future wireless communications and space communications. Millimeter wave signals are widely used in many occasions, such as broadband wireless communication, Atacama Large Millimeter Array ((ALMA), radar, millimeter wave imaging, fiber...
