Abstract

The invention discloses a microwave frequency source component with low phase noise and high spurious suppression and a usage method thereof. The component comprises a crystal oscillator 1, a power splitter 2, a phase discriminator A3, a loop filter A4, a voltage controlled oscillator A5, a coupler A6, a filter A7, an amplifier A8, a filter B10, a filter C12, a phase discriminator B13, a loop filter B14, a voltage controlled oscillator B15, a coupler B16, an amplifier B17, a filter D18, a mixer 9 and a comb generator 11. The microwave frequency source component has the advantage of easiness inimplementation. A mixer phase-locked loop design technology is adopted, mixing processing is placed in a phase-locked loop, and feedback frequency is reduced by mixing, so that phase noise is reduced; mixing spuriousness is filtered by the phase-locked loop filter; and the microwave frequency source with low phase noise and high spurious suppression can be realized.

Description

technical field [0001] The invention relates to a microwave frequency source component with low phase noise and high stray suppression and a using method. Background technique [0002] Previous microwave frequency source components were mainly composed of crystal oscillators, phase detectors, loop filters, voltage-controlled oscillators, couplers, amplifiers, and filters. It is difficult to realize multi-frequency microwave frequency sources with a single phase-locked loop. Achieve low phase noise and high spurious rejection. Contents of the invention [0003] The purpose of the present invention is to provide a microwave frequency source assembly with low phase noise and high spurious suppression, which solves the problem that it is difficult for traditional microwave frequency source assemblies to achieve low phase noise and high spurious suppression. [0004] In order to solve the above technical problems, the present invention provides a microwave frequency source ass...
