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 multiplication circuit based on a planar Schottky diode and a manufacturing method thereof. Background technique [0002] As the operating frequency of the system extends to the microwave and millimeter wave bands, the required frequency becomes higher and higher. However, due to the influence of factors such as components and output power, there is often a lack of stable and effective signal sources in the microwave frequency band. The low frequency signal source with low output power and high frequency stability can achieve frequency multiplication through 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 sources. Microwave frequency ...
