Problems solved by technology
In a typical balanced frequency multiplier circuit, a terahertz Schottky diode straddles the input RF waveguide through a quartz circuit. Due to the limited width of the input RF waveguide, the number of anode junctions of the Schottky diode cannot be too large. Generally, there are 2 tube junctions or 4 tube junctions, which can not withstand too much input power

The invention discloses a Terahertz frequency-doubled balanced type frequency multiplication circuit, and relates to a device which generates oscillation via frequency multiplication or frequency division of an independent signal source in non positive frequency. The frequency multiplication circuit comprises an RF input waveguide, a quartz substrate and an output waveguide, two discrete multi-junction GaAS-based frequency multiplication diode assemblies which are bonded on the quartz substrate in a flip chip manner serve as a nonlinear frequency multiplication device, and are in DC reverse serial connection; each diode can selected two or four chips according to the frequency of the frequency multiplication circuit; the mode of a transmission electric field can be converted in a quartz circuit; and the frequency-doubled balanced type circuit is formed. A schottky diode assembly in the frequency multiplication circuit is separated from the input waveguide, the amount of diode junctions is not limited by the width of the input waveguide any more, and the input power bearing capability is improved compared with a traditional balanced type frequency multiplication circuit.
Description
technical field [0001] The invention relates to the technical field of a device for generating oscillation by multiplying or dividing an independent signal source with a non-positive frequency, in particular to a terahertz double frequency balanced frequency multiplying 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 unbal...
