Abstract

The invention provides a terahertz frequency band local oscillator based on the integrated structure of frequency multiplication links, comprising an upper cavity (1) and a lower cavity (2); the surface of the upper cavity (1) and the lower cavity After the surfaces of the cavity (2) are closely attached, an input port (22), a Y-shaped power divider (17), a first pre-stage frequency doubler (19), a second pre-stage frequency doubler (20 ), a Y-type combiner (18), a post-stage frequency doubler (21) and an output port (23). On the basis of the balanced frequency doubler circuit, the above-mentioned local oscillator integrates the two-stage frequency doubler circuit into the same cavity module. While making the structure compact, it overcomes the reflection caused by the connection of different modules due to the port surface, and improves The performance of frequency doubling is improved, so that the W-band source can be frequency-multiplied to the terahertz frequency band to obtain greater output power.

Description

technical field

[0001] The invention relates to the technical field of local oscillators, in particular to a local oscillator in the terahertz frequency band based on an integrated structure of frequency multiplication links. Background technique

[0002] Terahertz waves are located between microwaves and infrared, and are electromagnetic waves with frequencies in the range of 0.1THz to 10THz. Since the 1920s, people have gradually recognized and carried out research on terahertz technology. After a certain amount of technology accumulation, there has been an upsurge in research and development in the past ten years. In 2004, the U.S. government rated terahertz technology as one of the "Ten Technologies That Will Change the Future World"; the following year, my country also held the "Xiangshan Science and Technology Conference" to formulate a development plan for terahertz technology. At present, universities, enterprises and research institutions in many countries around t...
