Terahertz frequency multiplier structure based on boss type quasi-waveguide filter

Abstract

The invention discloses a terahertz frequency multiplier structure based on a boss type quasi-waveguide filter. The terahertz frequency multiplier structure comprises an input waveguide, an output waveguide and the boss type quasi-waveguide filter located between the input waveguide and the output waveguide. The boss type quasi-waveguide filter comprises a waveguide shielding cavity (1), a quartzsubstrate (2) and a suspended microstrip conduction band (3), the quartz substrate (2) and the suspended microstrip conduction band (3) are arranged in the waveguide shielding cavity, the suspended microstrip conduction band (3) is arranged on one side surface of the quartz substrate (2), and a plurality of boss structures (4) are arranged on the other side surface of the quartz substrate. According to the invention, by introducing a multi-stage boss supporting form, more supporting areas are provided for the substrate, and by innovatively adopting a boss type quasi-waveguide filter structure,a filtering effect is introduced while the substrate is supported. The structure provided by the invention has the characteristics of small size, easiness in implementation and the like, and has a good application prospect in a terahertz wave frequency multiplier.

Description

technical field [0001] The invention relates to a terahertz frequency multiplier structure based on a convex platform quasi-waveguide filter. Background technique [0002] Electromagnetic waves with a wavelength of 3mm to 30um are called terahertz waves. The long-wavelength band is adjacent to millimeter waves, and the short-wavelength band is close to infrared rays, which is in the intersection area of ​​electronics and photonics. Compared with microwaves in lower frequency bands, their characteristics are: 1. The spectrum range used is wide and the information capacity is large. 2. It is easy to realize narrow beam and high-gain antenna, so it has high resolution and good anti-interference. 3. Strong ability to penetrate plasma. 4. Large Doppler frequency shift, high speed measurement sensitivity. Terahertz waves are of great significance in communication, radar, guidance, remote sensing technology, radio astronomy and spectroscopy. [0003] The frequency multiplier is...

AI Technical Summary

Problems solved by technology

Because the realization of solid-state frequency multiplier mainly uses microwave semiconductor devices, and microwave semiconductor devices in the terahertz frequency band are extremely small, and domestic frequency multiplier circuits are often assembled manually, which can easily lead to concave deformation of the substrate and reduce output. In order to obtain higher and stable output power, the substrate can only be shortened to prevent deformation
