Varactor-tuned frequency doubler oscillator

摘要

the invention relates to a microwave oscillator. to double the frequency of an oscillator in a single field effect transistor (10), whose fundamental frequency is determined by an impedance matrix (13), and an impedance of a source (15), we get a filter (16 + 17) between the drain of the transistor (10) and the mass.the filter is formed by a self (16) in series with a varactor (17) is set to the fundamental frequency, is just making sure the rejection and promotes the generation of the second harmonic, frequency.
