声表面波滤波器在5G n79频段的温度稳定性对于保证系统的性能至关重要。本文分析了声表面波滤波器在n79频段内工作时所面临的温度变化问题，探讨了其温度特性及影响因素，并提出了一些优化设计方案。通过对比不同设计方案的效果，本文深入讨论了如何在保证信号质量的提升温度稳定性，确保滤波器在不同温度条件下的可靠性。优化设计不仅能提升5G系统的整体性能，还能为未来的滤波器设计提供指导。
The temperature stability of surface acoustic wave (SAW) filters in the 5G n79 band is crucial for ensuring system performance. This paper analyzes the temperature variation issues faced by SAW filters when operating in the n79 band, explores their temperature characteristics and influencing factors, and proposes several optimized design schemes. By comparing the effects of different design schemes, this paper discusses in depth how to improve temperature stability while ensuring signal quality, thus ensuring the reliability of filters under varying temperature conditions. The optimized design can not only enhance the overall performance of 5G systems but also provide guidance for future filter design.
