Abstract

The invention discloses a terahertz multifunctional device based on an integrated technology. The terahertz multifunctional device comprises a terahertz doubler and a terahertz harmonic mixer. The device is structurally and sequentially provided with an input fundamental wave waveguide micro-strip transition, a micro-strip line short plane, a four-tube-core frequency-multiplication diode, a local oscillator matching circuit, a mixing diode, a radio-frequency matching circuit, an input radio-frequency waveguide micro-strip transition and a medium-frequency low-pass filter from left to right. The number of dielectric substrates is reduced so that circuits can be integrated on one substrate, the number of cavities to be machined is reduced as well, and machining and assembly are made simple; design and machining of waveguide transition are omitted, and the size of the cavities is reduced.

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...
