BROADBAND HIGH-EFFICIENCY LOCAL OSCILLATOR-INTEGRATED T-SHAPED TERAHERTZ MIXER - 41ST INST CHINA ELECTRONICS TECH GROUP CORP

Title:

BROADBAND HIGH-EFFICIENCY LOCAL OSCILLATOR-INTEGRATED T-SHAPED TERAHERTZ MIXER

Document Type and Number:

WIPO Patent Application WO/2018/090434

Kind Code:

A1

Abstract:

Disclosed in the present invention is a broadband high-efficiency local oscillator-integrated T-shaped terahertz mixer, which relates in particular to the technical field of terahertz-frequency spectrum. The broadband high-efficiency local oscillator-integrated T-shaped terahertz mixer includes an upper cavity and a lower cavity; the upper cavity and the lower cavity abut to form a waveguide structure; a T-shaped circuit is disposed in the upper cavity, and the T-shaped circuit comprises a radio-frequency (RF) signal path, a local oscillation signal path and an intermediate-frequency signal path; the RF signal and the local oscillation signal are combined at an antiparallel diode after the respective paths thereof; the local oscillation signal path comprises: a local oscillation input port, a local oscillation low-pass filter, a frequency multiplier, a local oscillator high-pass filter and a local oscillation duplexer; an output end of the antiparallel diode is connected sequentially to the intermediate-frequency filter and an intermediate-frequency output port.
