A right-hand nonlinear transmission line microwave frequency multiplication circuit is formed by 23 right-hand nonlinear transmission line units which are connected in series with each other. The each right-hand nonlinear transmission line unit is formed by the parallel schottky diodes and two segments of the same transmission lines which are connected in series. By using the right-hand nonlinear transmission line microwave frequency multiplication circuit provided in the invention, a circuit structure can be optimized; a peripheral bias circuit can be simplified. By using the manufacturing method of the right-hand nonlinear transmission line microwave frequency multiplication circuit provided in the invention, a corresponding circuit manufacturing technology can be simplified so as to improve harmonic output power of the frequency multiplication circuit. Harmonic wave conversion efficiency can be increased. A narrow-band harmonic-wave output characteristic can be improved and a harmonic wave output purity can be increased too. The method has many other characteristics.

Description

technical field [0001] The invention relates to the technical field of microwave circuits in microelectronics, in particular to a right-hand nonlinear transmission line microwave frequency doubling circuit based on planar Schottky diodes and a manufacturing method thereof. Background technique [0002] As the operating frequency of the system extends to the microwave and millimeter wave bands, the frequency is required to be higher and higher. However, due to the influence of devices, output power and other factors, there is often a lack of stable and effective signal sources in the microwave frequency band, which requires the frequency to be higher. Low-frequency signal sources with low power, high output power and high frequency stability are frequency-multiplied by nonlinear devices, such as varactor diodes, high electron mobility transistors, and heterojunction bipolar transistors. High-frequency frequency multipliers are widely used in the generation of microwave signal...
