Abstract

The invention discloses a terahertz multifunctional device based on integrated technology, including a terahertz frequency doubler and a terahertz harmonic mixer. Its structure from left to right is: input fundamental waveguide microstrip transition, microstrip line short-circuit surface, four-tube frequency-multiplier diode, local oscillator matching circuit, mixing diode, RF matching circuit, input RF waveguide microstrip transition, IF low pass filter. The number of dielectric substrates is reduced so that the circuit is integrated on one substrate, which also reduces the number of cavities to be processed and makes the processing and assembly simple. On the other hand, the invention reduces the design and processing of waveguide transitions and reduces the cavity size. size.

Description

technical field [0001] The present invention relates to the technical field of terahertz, and specifically refers to a terahertz multifunctional device based on integrated technology. Background technique [0002] Terahertz devices are an important part of terahertz technology, and they are carriers for propagating terahertz waves to realize terahertz systems, especially terahertz frequency conversion devices are the most important thing in the development of terahertz technology. Since it is very difficult to design and study a stable local oscillator source in the terahertz frequency band, it is of great practical significance to apply a low-frequency power source to the terahertz frequency band by using a frequency conversion circuit. Most of the currently studied terahertz circuit devices are single devices, which can only achieve a single function of frequency multiplication or frequency mixing, and are cascaded or paralleled on the basis of a single device to realize a...
