Abstract

The invention discloses a single-sided quartz fin line double diode terahertz balanced type frequency doubling circuit, and relates to the technical field of a frequency multiplying conversion circuit. The circuit includes a quartz substrate fin line circuit, two GaAs-based terahertz Schottky diodes reversely connected in series, a radio frequency input waveguide and a radio frequency output waveguide. The quartz substrate fin line circuit includes a quartz circuit substrate and front and back side fin lines located on the quartz circuit substrate. The two Schottky diodes are electrically connected with the front side fin line at one end and with the back side fin line at the other end. The Schottky diodes are located at the position where the distance between the front and back side fin lines remains unchanged. The circuit allows the radio frequency input and output waveguides to be one the same straight line to facilitate the design of the circuit personnel, meanwhile, the processing becomes easier, high power input can be withstood, and the output power is increased.

Description

technical field [0001] The invention relates to the technical field of multiple frequency multiplication conversion circuits, in particular to a single-sided quartz fin line double diode terahertz balanced double frequency multiplication circuit. Background technique [0002] In a broad sense, terahertz (THz) waves refer to electromagnetic waves with frequencies in the range of 0.1-10THz, where 1THz=1000GHz, and some people think that THz frequencies refer to electromagnetic waves in the range of 0.3THz-3THz. THz waves occupy a very special position in the electromagnetic spectrum, and THz technology is recognized as a very important cross-frontier field by the international scientific and technological community. [0003] It is an effective way to expand the terahertz frequency source based on solid-state electronic technology. At present, there are mainly two types of circuits used for terahertz frequency multiplication: balanced and unbalanced. During the development of...
