Eminent surpasses the difficult point that technology of small MAX-SAW filter upgrades

Technology of filter of Zhuo Shengwei MAX-SAW upgrades be faced with precision of patent camp, craft to ask difficulty of research and development of tall, material is great wait for difficulty, specific as follows:

• Patent camp is broken through hard: The village field place that make is aimed at filter of Zhuo Shengwei MAX-SAW (TF-SAW) mention patent lawsuit, show its violate 5 core patent continuously, involve the design that fold a layer, tilt the respect such as structure of IDT electrode, Piston. Village cropland has complex across to protect strategy on TF-SAW technology course, systematization of its patent network, the successor is very difficult avoid, this small to Zhuosheng technology upgrades formed serious patent limitation, if cannot be answered effectively, may affect its technology to upgrade direction and product are commercialized.
• Craft precision demand is extremely high: MAX-SAW filter function promotes those who rely on craft precision to rise, if need the structural parameter of electrode of fine adjustment IDT, reduce electrode further wide wait with clearance width. In the meantime, photoetching, etch, the craft such as deposit also needs to be improved ceaselessly, in order to raise craft precision and consistency, this controlled a technology to raise very tall requirement to craft, a bit deviation affects the function of filter and fine rate possibly.
• Difficulty of material research and development is great: Although POI underlay already made MAX-SAW filter function gets promotion, but to satisfy more high-powered requirement, still need to explore new underlay material or optimize existing POI underlay. Study the diamond stuff that has higher velocity of sound, better thermal conductivity and hear resistance for example, break through bottleneck of its preparation technology to apply at filter production to be not easy thing however, need investment of much research and development and technology to accumulate.
• High frequency function optimizes difficulty: Develop to 5G and even 6G as communication technology, need filter maintains good performance below more high frequency rate. Research of this demand development is high frequency paragraph signal is transmitted and filter baud sex, development optimizes design method and technical measure in the light of what high frequency applying, the choice that involves transmission of magnetic field of pair of high frequency report, sound wave to wait for complex physics phenomenon allows to understand and be controlled, technical difficulty is greater.
• Compositive technology challenge is much: To satisfy 5G the domain such as communication is opposite miniaturization of group of model of radio frequency front, high-powered demand, those who need to strengthen filter and component of front of other radio frequency is compositive. This should rise not only compositive degree, optimize compositive craft even, reduce the interference between different component, ensure systematic stability and dependability, work in coordination in what each package implements inside limited space, it is a complex systematic project.
