[Abstract]:With the popularity of wireless network applications such as mobile terminals, the wireless communication market is experiencing rapid growth. Driven by the market, the future wireless communication systems need to have the advantages of faster data transmission rate, higher working frequency band and lower power consumption and low cost. The oscillating source provides the signal and energy for the whole system, and its function in the wireless communication system is irreplaceable. Therefore, it is of great significance for the development of the high performance oscillator working in the microwave and millimeter wave frequency band. Based on the theory of microwave oscillation, the working principles of parallel feedback oscillator and series feedback oscillator are described, and the circuit structure of series feedback and parallel feedback double push oscillator is analyzed. In addition, the phase noise theory of the oscillator and the design method of the substrate integrated waveguide resonator are also introduced. Based on the substrate integrated waveguide resonator, an X band parallel feedback oscillator and a series feedback voltage controlled oscillator with center frequency of 10GHz are designed and implemented. In order to improve the phase noise performance of the oscillator, an X band series feedback oscillator based on active substrate integrated waveguide resonator is proposed. On the basis of parallel feedback oscillator and series feedback oscillator, two kinds of K-band double-push oscillators are designed to break through the upper working frequency of transistors. Finally, this paper introduces the design method and debugging process of series feedback voltage controlled oscillator in detail. Finally, the 10GHz phase-locked frequency source is realized. Based on microwave oscillation theory, substrate integrated waveguide technology and various electromagnetic simulation software, the oscillator and phase-locked frequency source are designed and machined. The test results reach the expected target of the subject, which shows that the theoretical analysis of this design is correct. The design scheme is feasible.
