Abstract

The invention discloses a high-order odd harmonic THz source frequency multiplier, and aims to provide a frequency multiplier which is simple in structure, high in efficiency and capable of effectively providing terahertz signals. The high-order odd harmonic THz source frequency multiplier is implemented according to the technical scheme that an external radio frequency signal is inputted through a standard rectangular waveguide (1), gets into a local oscillator low-pass filter (3) through an input waveguide-microstrip transition structure (2) and then enters a Schottky diode. Meanwhile, the external part performs feed excitation on the Schottky diode through direct current feed of a fundamental wave low-pass filter (4). The Schottky diode performs frequency conversion on input fundamental waves to generate high-order harmonic waves which comprise odd harmonic components and even harmonic components, finally the high-order harmonic waves get into an output waveguide (7) through an output microstrip-waveguide transition structure (6), the waveguide is lowered, a high-pass filter for filtering the even harmonic waves is formed, and output is performed through the standard rectangular waveguide. The high-order odd harmonic THz source frequency multiplier solves a problem of realizing a terahertz signal source.

Description

technical field [0001] The present invention is about fields closely related to social development, which can be widely used in broadband communication, radar, medical imaging, object imaging, non-destructive detection, astronomy, environmental monitoring, safety inspection, anti-terrorism detection, near-space communication / satellite communication and radar detection. An odd-order solid-state frequency multiplier in the terahertz frequency band. Background technique [0002] The terahertz frequency band is rich in resources, and the frequency band is located between microwave and millimeter wave and infrared optics, which are relatively well developed in science and technology. It has the advantages of large communication capacity, small system size, and good confidentiality. In addition to meeting the needs of short-distance and large-capacity ground communication, terahertz communication technology can also be used in space communication and signal detection. In the appl...
