Abstract
The present disclosure provides a hetero-integrated terahertz low-noise miniaturized image frequency rejection transceiver front-end, including an intermediate frequency circuit and a terahertz circuit arranged up and down, where the terahertz circuit includes a local oscillator frequency tripler, a 135° 3 dB filter coupler, a radio frequency waveguide power divider, and two quartz hetero-integrated subharmonic mixers; resonant cavities of an input unit, a first output unit, an isolation unit, and a second output unit of the 135° 3 dB filter coupler are sequentially coupled through resonant grooves to form a ring structure, a cavity length of the resonant cavity of the input unit is twice that of the resonant cavities of the other three units, and an electrical length of a waveguide of the first output unit is 45° different from that of a waveguide of the second output unit.
