- Abstract
To solve the problem t hat the assembly and debugging process of Yttrium Iron Garnet (YIG) sphere notch filter based on sphere coupled resonance is complex and not conducive to multi-channel integration, a structure and design method of YIG single crystal thin film notch filter implemented by magneto-static wave(MSW)technology is proposed in this paper. A practical YIG single crystal thin film notch filter with the tunable operating frequency range of 6~ 8 GHz was designed based on analyzing the operating principle of the single crystal thin film notch filter and optimizing the numerical calculation and device simulation of the angular frequency and wave number Cork) dispersion characteristics of magnetostatic backward bulk wave and magnetostatic wave excitation characteristics of microstrip excited resonant transducer. The simulation and experimental results show that the notch filter can ensure good pass-band insertion loss, stop-band depth and 30 dB stop-band bandwidth, etc. in the tuning band of 6~8 GHz.
