Abstract

The invention discloses a terahertz subharmonic frequency doubling and mixing device based on a monolithic integrated circuit. The device comprises a fundamental wave input waveguide micro-strip transition, a CMRC structure local oscillator low-pass filter, a frequency doubling matching circuit, a four-die frequency doubling diode, a local oscillator matching circuit, a frequency mixing diode, a radio frequency matching circuit, a radio frequency input waveguide micro-strip transition, and a CMRC structure intermediate frequency low-pass filter. According to the terahertz subharmonic frequency doubling and mixing device based on the monolithic integrated circuit, on the one hand, the number of dielectric substrates is decreased, and circuits are integrated on one substrate, so that the number of cavities to be processed is decreased, and processing and assembling are easy; on the other hand, waveguide transitions to be designed and processed are reduced, and the cavity size is reduced.

Description

technical field [0001] The present invention relates to the technical field of terahertz, and specifically refers to a terahertz subharmonic frequency multiplication and mixing device based on a monolithic integrated circuit. Background technique [0002] As a frequency conversion device, the subharmonic mixer plays an important role in the field of terahertz applications, but it is difficult to manufacture high-frequency sources in the terahertz frequency band and the power is low. Therefore, it is an important technical problem to solve the local oscillator source of the subharmonic mixer. In the prior art, in order to obtain a local oscillator source in the high frequency band, frequency multiplier components are needed to convert low frequency to high frequency, but in reality, frequency multipliers and mixers are designed and processed separately as separate components. Therefore, it takes up a lot of space, and requires two substrates with different widths to carry th...
