Abstract. This work addresses the problem of creating a compact, high-speed, low-noise microwave fre-quency synthesizer. A solution is proposed in the form of a detailed description of a promising synthesizer architecture. Brief information is provided on the main frequency synthesis methods, and the advantages and disadvantages of each method are analyzed. A definition of the hybrid frequency synthesis method is formulated. Computer simulation results are presented that confirm the advantages of a hybrid architecture combining phase-locked loop (PLL) and direct digital synthesis (DDS) techniques, enabling signal genera-tion over a wide frequency range while achieving low phase noise and preserving high speed and other ben-efits.

Keywords: microwave synthesizer, phase noise, hybrid frequency synthesizer
