国产滤波器的破局：TF SAW能否担此大任？The Breakthrough of Chinese Filter: Can TF SAW Take on the Responsibility?
➀ 滤波器是无线通信的核心组件，在数字智能时代，其作用愈发关键。国内资本的涌入和近两年的行业竞争导致了国产滤波器的困境。➁ 以TF SAW为代表的新技术路线被认为是实现国产化的“最佳途径”。➂ 然而，需要从技术、成本、市场及专利等多个角度对TF SAW进行评估。文章还指出了关于TF SAW的三大误区，包括其依赖于衬底材料、可能导致同质化内卷，以及TF SAW并非国产化的超车道，而是村田和高通的弯道。➀ Filters are critical components in wireless communication, with their role becoming increasingly significant in the digital intelligent era. The entry of domestic capital and the fierce competition in the past two years have led to the current predicament of domestic filters. ➁ The TF SAW technology, represented by new routes, is considered the 'best way' to achieve breakthroughs in domesticization. ➂ However, it is necessary to evaluate TF SAW from multiple dimensions such as technology, cost, market, and patents. ➃ The article also points out the three major misunderstandings about TF SAW, including its dependence on substrate materials, the potential for homogenization and internal competition, and the fact that it is not a superhighway for domestication but a detour for Murata and Qualcomm.
