Description

technical field [0001] The invention relates to solid-state terahertz technology, in particular to a broadband terahertz harmonic mixer. Background technique [0002] In the field of solid-state terahertz, the development of a qualified harmonic mixer is the basis for the study of communication systems. With the continuous development of terahertz communication technology, terahertz harmonic mixers are constantly developing to higher frequency bands. In the high-frequency band, the quartz substrate carrying the circuit and the cavity where the circuit is placed will become smaller, resulting in a gradual increase in processing accuracy and assembly difficulty. The existing inverted diode pair with gallium arsenide substrate has been unable to meet the design requirements of the wide frequency band of the high frequency harmonic mixer. In the traditional upside-down diode pair circuit, the diode pair is processed on a gallium arsenide substrate, and then upside down in the ...
